Greetings,

My apologies if this is a very simple question. I downloaded and installed a couple of packages today. In the package manager in R for Mac (version 2.7.2), I find that when I try to load the package, I can't. The load button never clicks on. Why is that?

Because there is apparently a problem with that package. Check the console for results. Clicking on the checkbox (there is no load button afaics) simply issues a "library" command and the checkbox itself represents the real state of the package so if it failed to load for nay reason, it will stay unchecked.

Cheers,
Simon


 As an example, I'm trying to use Ryacas.  Thanks in advance,

David
