Installing R for Windows

The following steps shows how to download and install R on windows:

The first step is to download your required version of R from the CRAN website [http://www.rproject.org/].
Go to the official R website, which you can find at https://www.r-project.org/.
The download link can be found on the left-hand side of the page.
The next option is for you to choose the location of the server that holds R. The best option is to choose the mirror that is geographically closest to you. For example, if you are based in the UK, then you might choose the mirror that is located in Bristol.
Once you click on the link, there is a section at the top of the page called Download and Install R. There is a different link for each operating system. To download the Windows-specific version of R, there is a link that specifies Download R for Windows. When you click on it, the download links will appear on the next page to download R.
On the next page, there are a number of options, but it is easier to select the option that specifies install R for the first time.
Finally, there is an option at the top of the page that allows you to download the latest R installation package. The install package is wrapped up in an EXE file, and both 32 bit and 64 bit options are wrapped up in the same file.
