pat	the pattern of R .exe file to download
to_checkMD5sums	Should we check that the new R installation has the files we expect it to (by checking the MD5 sums)? default is TRUE. It assumes that the R which was installed is the latest R version.
keep_install_file	If TRUE - the installer file will not be erased after it is downloaded and run.

silent	If TRUE - enables silent installation mode.

Details

If you are not sure if you need to update R or not, It is better to use updateR for updating R, since it includes more options. But in case you wish to only install R, with no other steps taken (for example, taking care of your old packages), then you can use install.R()

See the install.Rdevel function for installing the latest R-devel version.

Value

TRUE/FALSE - was the installation of R successful or not.
