[R] unable to access index for repository...

[Steven Yen]

I had to install/use an older version of (R-3.0.3) for a reason. While 
installing a package from CRAN (either in RStudio or R), I received the 
following warning message saying unable to access index for repository 
http://cran.rstudio.com/bin/windows/contrib/3.0. See message below. In 
this case, I tried to install "aod". The install nevertheless went 
through, as confirmed by the library statement (I did not try to use 
it). Any idea? Thank you.
