I'm here to help you about installation of RStudio and Rattle package which we are going to use in the module of iMBA in Coursera. So, let's see. Rattle is a package which is built on R platform. It is a GY version which basically helps you to avoid writing code in R and directly go to focus on your analysis. So before going to Rattle, we first have to install R and RStudio, which are the base packages. So, let's first download it. Let me go to Google. Here I say "download r". Here you see download for Windows. I'm just copy-pasting this org. It's cran.r-project.org. This link is available in the module, in the instruction manual as well. Here you click on "Download R for Windows". If you are using a Linux machine, or a Mac OS, you can go and download the appropriate software as well. So, let's click on "R for windows". Here you'll find a link called "install R for the first time". Let's go and click here. Here you will see "Download R". This will always be the latest version. If you want to go for the previous releases, you have to go here in the bottom. We will recommend you to use the latest version of Rattle. In case you face any difficulty in using Rattle, R, or RStudio, you can go back and refer that this version should be updated. So let me click here. Now it's asking me to "Save file". Let me "Save file". Here you can see. We'll do it for 25 more seconds. You can directly open file by clicking here as well, ask you to permission to install the software. Here select language. I will reccomend go ahead and just read the condition. If you agree, click "Next" until you want to customize anything in terms of destination, location, the type of component you want to use: 32-bit, 64-bit. Accept default, create folder, create Startup menu, everything. Let's go ahead and stop. See, it's installed. Now let's go and search for RStudio. So I typed "download rstudio", I go to RStudio website. It gives you multiple different product type of RStudio. We are going to RStudio Desktop which is a free version open-source downloadable for academic purpose. Let's go ahead and download RStudio Desktop. Here you see the installers are available for different operating systems: Windows 7 and above, Mac Operating System, Ubuntu, and many more. I'm downloading Windows 7 because I'm using Windows 10 in the system. So, let's go ahead and download it. It's super fast. Let's go and click on "RStudio" here in the top. It will ask you to install it. Again, if you want to customize anything, you can do that or simply click. Might be wondering why are we going through so many softwares just to use Rattle. Rattle is just a graphical user interface for data mining in R. If you are comfortable with coding, you can use R in RStudio directly, you need not to install Rattle. Since we want you to focus more on data mining concepts rather than focusing on programming, we thought to use Rattle in this course. So now that RStudio is installed, you can simply go and let's open RStudio. So, let me click here. So, this is our RStudio interface. Let me show you how to install Rattle here. So, first you have to install the package. So, we'll say "install.packages". Before installing Rattle, we have to install RGtk2. Please note. This is case sensitive. RG is capital, tk2 is small. Let's start. Let's install RGtk2. Here we go. RGtk2 is installed. Now to go further, we have to install. Let's activate RGtk2. So, when you try to activate it, it asks you whether you want to install GTK+ as well. So please do this. Install GTK+. So, to install, I'd suggest you restart R before trying to load the package again. So, let's go back. This is RStudio again. Now let's try and load the package again. Let's type "library RGtk2". Now you see it doesn't ask you. Fantastic. Now we have to install Rattle package so we'll type 'install.packages("rattle")' all small. So, it's installed. Now let's activate it library("rattle"). Now lets run this. You click on "Rattle". This is how you get the Rattle interface.
