Hello, I'm trying to upgrade R from 3.0.3 to 3.1 on MacBookPro Mavericks 10.9.2. After downloading R-3.1.0-mavericks.pkg from http://cran.stat.ucla.edu/ and clicking it, I get the following error message:
"R-3.1.0-mavericks.pkg can't be installed because its digital signature is invalid". I checked the md5 signature with md5sum and it matches that found on the download page. I also tried re-downloading the package from different mirror sites and I get the same error. I also tried R-3.1.0-snowleopard.pkg but I got the following error: "This package was signed with an invalid certificate. This package might not install what you expect." But unlike the mavericks.pkg, the snowleopard.pkg provides me the option to continue the install in spite of the warning. Why am I getting these 'invalid' warnings? How do I securely and properly install R 3.1 on my Mac that is running Mavericks? It is strange that just a few weeks ago, I did not have these problems installing R 3.0.3. Thank you for your help, Paul P.S.
