R help - Feb 2015 - Issue wit Package installation and download.file()

Hello,

I have installed RStudio Version 0.98.1091, R version, R Version 3.1.2, on
my Windows 7 desktop (64 bit). I am using wifi without any proxy server.

Issues:-

1. I am unable to install the packages from CRAN mirror(India). I am
getting the below error:-

*Warning: unable to access index for repository
http://ftp.iitm.ac.in/cran/bin/windows/contrib/3.1

port 80.*
*2: package ?devtools? is not available (for R version 3.1.2) *



2. I am unable to download file using method * download.file() *
I get the below error:-

trying URL '
https://archive.ics.uci.edu/ml/machine-learning-databases/iris/iris.data'
Error in download.file(url, file) :
  cannot open URL '
https://archive.ics.uci.edu/ml/machine-learning-databases/iris/iris.data'
In addition: Warning message:
In download.file(url, file) :
  InternetOpenUrl failed: 'The server name or address could not be
resolved'


Action Taken:-
I have execute the following command in Rstudio:-

*Sys.setenv(http_proxy="")*

and I have created the .Reniron file in the home directory that contains
*Sys.setenv(http_proxy="")*


Issue is still the same.
Please help me!
