在Mac OSX雪豹上更新后，install.packages（）出现问题

Question

Earlier today I updated R to 2.14.2 so that I could install the new ggplot2. Now I'm getting the following error anytime I try and use install.packages():

Warning in install.packages :
package ‘foo’ is not available (for R version 2.14.2)

I've tried to rectify my mistake by removing R and installing an older version. I used the command:

rm -rf /Library/Frameworks/R.framework /Applications/R.app

Even after that reinstallation I got the same error (using 2.14.1 and 2.14.0).

Is this a problem anyone else is having on snow leopard?

Answer 1

I had the same issue tonight. After reading your post and checking R-sig-mac, it appears that there was a sync problem to all the mirrors. In fact, the PACKAGE file for 2.14 for contributed packages on all these mirrors are empty. Util this is fixed, you can try hit the master site by setting

repos = 'http://cran.r-project.org'

inside the install.packages() call.

I just tried and it works.
