00:00:06,780 --> 00:00:12,150 a tour of the various functionalities that our studio will provide when you're programming in our programming 3 00:00:12,150 --> 00:00:13,500 language. 4 00:00:13,500 --> 00:00:17,010 Let's go ahead and jump to our studio now. 5 00:00:17,010 --> 00:00:17,520 All right. 6 00:00:17,520 --> 00:00:19,400 So here we are our studio. 7 00:00:19,560 --> 00:00:24,370 And you'll notice we have various panes or windows open within our studio. 8 00:00:24,420 --> 00:00:30,570 We have the console here on the left and we also in an environment and a history tab. 9 00:00:30,570 --> 00:00:33,920 Sometimes the environment is also known as a workspace tap. 10 00:00:34,260 --> 00:00:39,310 And here on the bottom right we have some files in this tab. 11 00:00:39,360 --> 00:00:44,660 So let's go ahead and just explain these various windows and screens and show you what they do. 12 00:00:44,730 --> 00:00:50,820 You may see some R code throughout this tour of our studio or if you don't fully understand it we'll 13 00:00:50,820 --> 00:00:53,970 teach you all about our programming later on in the course. 14 00:00:53,970 --> 00:00:58,380 Right now we're just giving you a basic feel for how to use our studio here on the left. 15 00:00:58,380 --> 00:01:00,090 We have the cons.. 16 00:01:00,180 --> 00:01:04,490 So the council is where we can type direct commands and see output. 17 00:01:04,500 --> 00:01:07,620 So we've actually already used this in the installation video. 18 00:01:07,650 --> 00:01:13,530 We'll go ahead and show another example that can do something like Prince. 19 00:01:13,700 --> 00:01:18,290 And you'll noticed you'll get a lot of helpful pop ups show up in our studio. 20 00:01:18,420 --> 00:01:24,570 So as you begin to type functions that exist in our our studio that will automatically pop up suggestions 21 00:01:24,630 --> 00:01:26,590 or auto complete code for you. 22 00:01:26,610 --> 00:01:30,770 So here it pops up some information about the print function. 23 00:01:30,990 --> 00:01:34,960 So go ahead and says something like print's it's arguments etc.. 24 00:01:35,340 --> 00:01:40,710 So we're going to do is do an open parentheses again you'll notice our studio automatically adds closing 25 00:01:40,710 --> 00:01:43,380 parentheses in a file type in a single quote. 26 00:01:43,500 --> 00:01:51,980 It automatically adds the closing quote and we'll just go ahead and say our studio is nice. 27 00:01:52,320 --> 00:01:54,920 I'll click enter and since is a con.. 28 00:01:54,950 --> 00:01:58,540 I have directly typed the command and I see the output directly. 29 00:01:58,710 --> 00:02:02,060 Now let's explore this environment tab right here. 30 00:02:02,220 --> 00:02:06,510 So this is going to show all the active objects in my environment. 31 00:02:06,750 --> 00:02:08,000 So what that means is I. 32 00:02:08,190 --> 00:02:15,150 As I assign various variables values so I'll have a bunch of variable names and they'll have different 33 00:02:15,150 --> 00:02:18,450 associated values to them or objects or data structures. 34 00:02:18,450 --> 00:02:20,760 This tab is going to go ahead keep track of that. 35 00:02:21,000 --> 00:02:29,280 So for example let's go ahead and start of a variable called a in a sign at the number 2. 36 00:02:29,310 --> 00:02:32,890 Don't worry about this syntax will go over it in much more detail later on. 37 00:02:32,940 --> 00:02:36,720 Basically here I'm just assigning to the variable a. 38 00:02:37,410 --> 00:02:42,710 I go ahead and click enter and now in my global environment I can see that I have some value. 39 00:02:42,800 --> 00:02:44,870 And it has been assigned to. 40 00:02:45,300 --> 00:02:46,050 All right. 41 00:02:46,200 --> 00:02:52,680 So here at the bottom right I have a file's tab so the spiles tab shows all the files and folders in 42 00:02:52,680 --> 00:02:57,560 your default workspace as if you're just on either a PC or Mac window. 43 00:02:57,600 --> 00:03:03,840 Also if you end up using plotting in our studio you can click here on the plot's tab and your plot's 44 00:03:03,840 --> 00:03:05,160 will show up here. 45 00:03:05,640 --> 00:03:12,840 The next tab which is the package's tab will list a series of packages or add ons needed to run a certain 46 00:03:12,840 --> 00:03:16,460 process will get into packages much later on in the course. 47 00:03:16,530 --> 00:03:19,020 So don't worry about them right now. 48 00:03:19,020 --> 00:03:23,610 Here you have the help tab which is really useful if you have some sort of internet connection or a 49 00:03:23,610 --> 00:03:27,170 downloaded the are resources or manuals needed. 50 00:03:27,180 --> 00:03:32,640 You'll always find all the help you need throughout this helped including great resources for learning 51 00:03:32,640 --> 00:03:32,680 . 52 00:03:32,690 --> 00:03:35,170 Are are learning more about our studio. 53 00:03:35,630 --> 00:03:39,900 OK so let's go ahead and explore the workspace a little more. 54 00:03:40,290 --> 00:03:46,650 So again I have this environment tab which is going to store any object value or functions that I create 55 00:03:46,680 --> 00:03:48,470 during my R session. 56 00:03:48,540 --> 00:03:54,880 So in the example below I already created a variable A and assigned the number to just an integer. 57 00:03:54,940 --> 00:04:00,270 But for example if I do let's go ahead and make a vector called the. 58 00:04:00,410 --> 00:04:05,790 And don't worry about the syntax here and just showing this for example purposes I create a new object 59 00:04:05,790 --> 00:04:05,810 . 60 00:04:05,820 --> 00:04:07,090 In this case it's a vector. 61 00:04:07,140 --> 00:04:13,420 And here I see more information about the different values I have existing in my environments. 62 00:04:13,440 --> 00:04:16,380 You'll notice that right next to this environment tab. 63 00:04:16,590 --> 00:04:21,550 I have a history tab and the history tab keeps a record of all your previous commands. 64 00:04:21,540 --> 00:04:25,370 And this really helps when testing or running various processes. 65 00:04:25,470 --> 00:04:30,720 Here you can either save the whole list or you can select commands you want and then send them to in 66 00:04:30,780 --> 00:04:36,390 our script to keep track of your work when you're using our studio. 67 00:04:36,420 --> 00:04:41,150 It's more likely that you're going to want to actually select a particular working that rectory here 68 00:04:41,150 --> 00:04:41,260 . 69 00:04:41,280 --> 00:04:43,670 I've already selected a working directory for this. 70 00:04:43,680 --> 00:04:48,180 Our code will let me go ahead and show you how you could change a working directory if you wanted to 71 00:04:48,180 --> 00:04:51,220 change your working directory for this particular session. 72 00:04:51,300 --> 00:04:59,430 You just go to this session and this top tab and then go to set working directory and then you can choose 73 00:04:59,430 --> 00:05:01,070 directory here. 74 00:05:01,140 --> 00:05:05,580 A window will pop up and then you can go ahead and choose the directory you want to go ahead and Slik 75 00:05:05,590 --> 00:05:06,220 cancels. 76 00:05:06,220 --> 00:05:12,320 Since I'm already at the folder I want to be in so again go into session set working directory choose 77 00:05:12,320 --> 00:05:15,300 their victory will allow you to change the working directory. 78 00:05:15,590 --> 00:05:21,230 But you can also set a default or can directory that's directory that's going to default to every time 79 00:05:21,230 --> 00:05:22,520 you open our studio. 80 00:05:22,790 --> 00:05:31,490 You can do that under the Tools tab so you can go to Tools go to Options or global options and then 81 00:05:31,490 --> 00:05:36,680 here you'll get a little options window pop up and then which you can do is go ahead and select a default 82 00:05:36,680 --> 00:05:41,100 working directory and then you can go ahead and click Browse and choose the folder. 83 00:05:41,110 --> 00:05:45,200 Make sheet click apply and then click OK. 84 00:05:45,200 --> 00:05:49,560 If you ever want to figure out what directory you're in there's two ways to do this. 85 00:05:49,580 --> 00:05:53,960 You can either just go ahead and check here under the files tab the directory or under. 86 00:05:53,960 --> 00:05:55,430 It'll show you the path. 87 00:05:55,430 --> 00:06:01,890 Or you can click here in the console and type G E T W D. 88 00:06:02,450 --> 00:06:06,100 Close parentheses and that will get the working directory which is what. 89 00:06:06,120 --> 00:06:10,790 There'll be the stands for if you click enter it'll show up as a response. 90 00:06:10,820 --> 00:06:12,660 And there's my working there victory. 91 00:06:13,610 --> 00:06:19,130 If you want to set your working directory or change or working directory directly from the console you 92 00:06:19,130 --> 00:06:28,280 can actually use set W.D. parentheses and then type in the directory of wherever you want to set. 93 00:06:28,310 --> 00:06:32,150 So you would just type in here the file path to whatever new directory you want. 94 00:06:32,240 --> 00:06:36,380 I will go ahead and run that since I'm already at the directory I want and I already did it using our 95 00:06:36,380 --> 00:06:39,440 studios graphical user interface. 96 00:06:39,470 --> 00:06:44,330 Now when you're developing in our program or in our script usually you're not going to just input a 97 00:06:44,330 --> 00:06:49,740 bunch of functions or commands directly into the console which you're going to be doing is working with 98 00:06:49,740 --> 00:06:51,200 an R script. 99 00:06:51,200 --> 00:06:55,730 So an R script is where are you going to basically keep a record of your work and be able to run multiple 100 00:06:55,730 --> 00:06:57,470 commands all at once. 101 00:06:57,480 --> 00:07:03,590 Now what you can do in order to start a new script is click here on this little icon and then go ahead 102 00:07:03,590 --> 00:07:08,880 and select our scripts later on we'll discuss things such as are marked down and shiny webapps. 103 00:07:09,030 --> 00:07:12,250 But let's keep it simple for now and go ahead and select our scripts. 104 00:07:12,460 --> 00:07:15,020 Now you can see we have four windows. 105 00:07:15,020 --> 00:07:18,840 This is what you'll almost always be using when you're dealing with our studio. 106 00:07:19,040 --> 00:07:24,650 So you have the console window the workspace or global environment that history window over here on 107 00:07:24,650 --> 00:07:25,700 the top right. 108 00:07:25,820 --> 00:07:30,230 You have the files plot's packages isn't help when though here at the bottom right. 109 00:07:30,440 --> 00:07:33,320 And here the top left you have your scripts here. 110 00:07:33,350 --> 00:07:39,050 My script is currently untitled so our script is we're going to basically keep a record of your work 111 00:07:39,050 --> 00:07:42,200 and be able to run a bunch of our commands all at once. 112 00:07:42,350 --> 00:07:46,680 So maybe if you're coming in from another language such as Python you can think of this is just a dot 113 00:07:46,780 --> 00:07:48,440 PI file. 114 00:07:48,440 --> 00:07:49,190 All right. 115 00:07:49,910 --> 00:07:54,970 Let's go ahead and see an example of using in our script to run some commands. 116 00:07:55,310 --> 00:07:58,420 So I'm going to go ahead and type out some R code. 117 00:07:58,430 --> 00:08:06,590 We'll just go ahead and use simple print statements saying the say print first line and then I'm going 118 00:08:06,590 --> 00:08:11,120 to go ahead on the second line of code here and go ahead and say print. 119 00:08:12,260 --> 00:08:13,460 Second line. 120 00:08:13,970 --> 00:08:14,810 All right. 121 00:08:14,810 --> 00:08:18,190 So here we have my our script. 122 00:08:18,200 --> 00:08:20,580 Notice right now it's untile and not saved. 123 00:08:20,770 --> 00:08:23,060 I go ahead and click this floppy disk icon. 124 00:08:23,090 --> 00:08:32,360 It will save it and it will have to name it's going to go ahead and say this is Demo click Save it automatically 125 00:08:32,600 --> 00:08:33,860 put the extension demo. 126 00:08:33,900 --> 00:08:35,150 Are here for you. 127 00:08:35,300 --> 00:08:38,390 So I have my script all ready to go. 128 00:08:38,390 --> 00:08:44,780 You'll notice here I have a run which is going to run the current line or selection and then I also 129 00:08:44,780 --> 00:08:51,290 have source which sources the contents of the active documents and in between those I have a rerun the 130 00:08:51,290 --> 00:08:53,110 previous code but. 131 00:08:53,930 --> 00:08:56,730 So let's go ahead and explore each of these buttons does. 132 00:08:56,960 --> 00:09:02,400 If I select here I can go ahead and highlight or just have my cursor on the first line. 133 00:09:02,570 --> 00:09:04,250 So print first line. 134 00:09:04,250 --> 00:09:05,900 If I go ahead and click run. 135 00:09:06,230 --> 00:09:11,430 Notice I just get here on my console which displays the output print first line. 136 00:09:11,480 --> 00:09:14,800 It didn't run everything in the script. 137 00:09:14,900 --> 00:09:22,060 And again if I have my cursor or if I highlight select the entire second line and then click run. 138 00:09:22,220 --> 00:09:26,940 It's just going to execute where the cursor was on that line. 139 00:09:26,960 --> 00:09:29,130 So it's only going to do one line at a time here. 140 00:09:29,300 --> 00:09:31,040 So that's what the run button does. 141 00:09:31,040 --> 00:09:33,860 It runs that either the entire selection you have. 142 00:09:33,860 --> 00:09:40,340 So if you highlighted a bunch stuff will run it or just the current line. 143 00:09:40,340 --> 00:09:46,550 Now if we go ahead and click here on the source you'll notice we get everything output. 144 00:09:46,550 --> 00:09:49,650 So this is basically going to run the entire source script. 145 00:09:49,670 --> 00:09:55,100 And in this case you can see here on the console we have first line second line and you'll notice here 146 00:09:55,100 --> 00:10:00,940 that the command was source and then it just relays the entire path to that dot our code. 147 00:10:01,430 --> 00:10:01,970 All right. 148 00:10:02,180 --> 00:10:11,150 So those are the basics of our studio writing our scripts and using the history in environments windows 149 00:10:11,240 --> 00:10:13,280 in our studio. 150 00:10:13,280 --> 00:10:18,950 As we begin to learn more about the our programming language we'll explore our studios other capabilities 151 00:10:18,980 --> 00:10:22,120 in more detail later on. 152 00:10:22,130 --> 00:10:28,190 The last thing I want to discuss is setting up customizing the appearance of our studio. 153 00:10:28,190 --> 00:10:30,560 So right now you'll notice the fonts pretty small. 154 00:10:30,650 --> 00:10:37,460 So when I'm teaching everyone in this course what I'm going to do is actually make the font larger and 155 00:10:37,550 --> 00:10:41,520 I'm going to go ahead and make the background dark instead of white. 156 00:10:41,540 --> 00:10:44,420 So let me go ahead and show you how to do that. 157 00:10:44,570 --> 00:10:51,650 You can just go to Tools Global Options and Global Options is the window where you're going to be able 158 00:10:51,650 --> 00:10:55,760 to change pane layouts Appearance's packages etcetera. 159 00:10:55,880 --> 00:10:57,570 So there's a lot of options here. 160 00:10:57,950 --> 00:11:04,220 And if you just click on appearance here you'll have the option to choose your editor font and your 161 00:11:04,220 --> 00:11:06,600 font size how much you want to zoom in. 162 00:11:06,650 --> 00:11:10,450 And there's some example code here and I'll show you what it looks like. 163 00:11:10,580 --> 00:11:15,300 So I'm going to go ahead and select the font to be a little bit larger. 164 00:11:15,350 --> 00:11:19,980 And if you go ahead and select Ed. themes you can change the color themes for you. 165 00:11:20,240 --> 00:11:24,090 So go in and select the theme that you like the best. 166 00:11:24,380 --> 00:11:26,720 I'm going to go ahead and select mano Kai. 167 00:11:26,810 --> 00:11:33,350 It's really similar to Sublime Text Editor if you're familiar with that text editor software and if 168 00:11:33,350 --> 00:11:36,380 you want you can also play around with the font. 169 00:11:36,530 --> 00:11:39,500 I'm going to go ahead and keep the default. 170 00:11:39,500 --> 00:11:48,500 So let's go ahead and apply that make this a little larger at 16 apply select OK and you can see I have 171 00:11:48,560 --> 00:11:54,080 changed the appearance of my scripts and my cons.. 172 00:11:54,350 --> 00:11:59,120 So choose whatever is most readable for you what you like the best. 173 00:11:59,240 --> 00:12:02,000 Obviously that's personal preference. 174 00:12:02,000 --> 00:12:02,570 All right. 175 00:12:02,690 --> 00:12:04,080 That's it for this lecture. 176 00:12:04,190 --> 00:12:07,390 Hopefully that was a nice little tour an overview of what you can do. 177 00:12:07,400 --> 00:12:09,530 Our studio and how to use our studio. 178 00:12:09,660 --> 00:12:14,080 So it's going to be our main development environment where we're learning how to program with our. 179 00:12:14,150 --> 00:12:18,960 Don't worry we didn't understand all the art commands or our code that I showed in this lecture. 180 00:12:18,980 --> 00:12:22,730 We're going to be covering all of that later on when we actually learn how to program it. 181 00:12:23,330 --> 00:12:28,970 This lecture was just for showing and exploring the art studio development environments. 182 00:12:29,030 --> 00:12:31,850 OK thanks everyone and I'll see you at the next lecture 19502
