Following this post and also this link , I tried to update my R version .
sessionInfo()
R version 2.14.0 (2011-10-31)
Platform: i386-pc-mingw32/i386 (32-bit)
locale:
[1] LC_COLLATE=English_United States.1252
[2] LC_CTYPE=English_United States.1252
[3] LC_MONETARY=English_United States.1252
[4] LC_NUMERIC=C
[5] LC_TIME=English_United States.1252
attached base packages:
[1] stats graphics grDevices utils datasets methods base
other attached packages:
[1] installr_0.9
loaded via a namespace (and not attached):
[1] tools_2.14.0
But when I ran the code
updateR()
Error in file(con, "r") : cannot open the connection
It shows exactly the same error while running the following command :
check.for.updates.R() # tells you if there is a new version of R or not.
Error in file(con, "r") : cannot open the connection
install.R() # download and run the latest R installer
Error in file(con, "r") : cannot open the connection
How can I update my R version ?

If you want to update R and RStudio: There, you can go to the “R” menu and click “Check for R Updates” (see image below). If you do that, R will tell you the current version you're on, and whether or not there is a more updated version that you can download (circled in blue).
The easiest way to update R is to simply download the newest version. Install that, and it will overwrite your current version. There are also packages to do the updating: updateR for Mac, and installr for Windows.
Upgrading your version of R If you decide to upgrade your version of R, simply choose a CRAN mirror in the download page and follow the procedure you used to initially download and install R. The installation will automatically install the new version and make it available within RStudio.
Per https://github.com/talgalili/installr/#troubleshooting,
Try running:
setInternet2(TRUE)
That worked for me when I was getting the below error message:
Error in file(con, "r") : cannot open the connection
