I got this error message working under R version 3.3.0 trying to use the Mac

R error message:
Warning: unable to access index for repository

I checked for upgrades and installed R version 3.3.1
I got the same error message once again.
Luckily I remembered that I could install libraries from within R and thus used:
install.packages('RCurl', dependencies=TRUE, repos='http://cran.rstudio.com/')
But I am wondering if the malfunction of the GUI approach is something I can
fix or is temporary?
That was probably a temporary problem, or a local network problem for
you: I can get the URL to open.
But in general, to change the default mirror in R.app, run
chooseCRANmirror() in the console. I forget whether that changes it for
the session or permanently.
