- [00:00:00.240]Hello in this quick tutorial we will first look into how do we install R on
- [00:00:06.043]our desktop and then we will also look into how do we install a program called
- [00:00:12.076]as R Studio which works with R and makes writing the R scripts much more easier
- [00:00:18.185]for us.
- [00:00:19.120]So without any further delay, let's take a look.
- [00:00:22.560]In order to install R, we will go to a website on our favorite
- [00:00:28.401]browser and we'll go to www. rminusprojectorg.
- [00:00:33.320]And then we can click on the CRAN link on the left side,
- [00:00:37.217]which says download packages.
- [00:00:39.600]And it actually takes us to a list of mirrors.
- [00:00:43.080]And I'm going to go down to USA and pick up the Berkeley Edu.
- [00:00:48.480]And since I am going to install R on my Windows machine,
- [00:00:53.285]I will click download R for Windows.
- [00:00:56.400]I will pick up the base install and once I click on that I go to download R 3.
- [00:01:05.347]0 point 2 for Windows and I will save as I'll save it on my desktop save and it is
- [00:01:14.747]downloading now.
- [00:01:17.200]So I have R downloaded completely on my desktop.
- [00:01:19.640]Here I'm going to double click and it says the publisher could not be verified.
- [00:01:25.640]I sure you want to run the software.
- [00:01:27.440]I'm saying yes and it is a User Account Control and I want it in English Next
- [00:01:44.262]next next next and I'm going to do make an default install and it will be many
- [00:02:01.300]folders of R and next we have finish.
- [00:02:10.000]So now since I did select to have a desktop desktop icon for R,
- [00:02:16.893]I'm going to start with RX64 and this is the default window that you see while in
- [00:02:25.725]order to interact with R So if I say 2 + 3, it gives me 5.
- [00:02:32.080]This basically shows that my R install works fine.
- [00:02:36.120]However, in order for us to make our workspace
- [00:02:39.496]more useful and more easier to interact with,
- [00:02:42.801]we will install another software as I mentioned in the beginning of the
- [00:02:47.974]tutorial and which is called as R Studio.
- [00:02:50.920]So for now, I'm going to close this window and it's
- [00:02:53.934]going to ask me save workspace image.
- [00:02:56.120]I'm going to say no and I'll go back to my browser and go to a website called www.
- [00:03:03.746]rstudio. com and I will this is the website how it
- [00:03:08.432]looks like and I will go to R Studio IDE.
- [00:03:12.240]IDE means integrated development environment and I'm going to say download
- [00:03:19.440]R Studio and click again.
- [00:03:22.520]And now the website was able to detect that I'm using a Windows machine for my
- [00:03:30.022]desktop and they recommend a Windows XP version of Vista or 7 or 8.
- [00:03:36.880]And I'm going to download this one save link as on the desktop and save and it's
- [00:03:46.739]downloading.
- [00:03:51.880]Once the download is complete, I'm going to install the Rstudio as well.
- [00:03:58.040]So Rstudio, same steps, next finish.
- [00:04:08.680]And now I have in all programs.
- [00:04:12.480]I have R Studio and I will launch R Studio and here we go.
- [00:04:18.600]So we have the same R console but it is now part of a bigger development
- [00:04:23.892]environment and I can start a new file.
- [00:04:27.520]So file new R script and I get an area and if I say 2 + 3 and I say run.
- [00:04:38.120]So it actually copies this statement that I wrote here and runs it in my R console
- [00:04:43.900]and gives me the result as 5.
- [00:04:46.400]So that's all for now.
- [00:04:48.920]And the goal for this short tutorial was to just get you started and make sure
- [00:04:54.049]that we have R installed on our desktop, in this case the Windows machine.
- [00:04:59.240]And in order to do that, what we did is we first install the R
- [00:05:03.929]distribution or the R software and then after R has been installed,
- [00:05:08.990]we install a studio on top of it, which is a development environment which
- [00:05:14.573]makes life easier for us to work with R and it is called R Studio.
- [00:05:20.360]Thank you so much.
