[R] could not load r package in mac

[Fox, John]

Dear Kristi,

>From a subsequent message, you appear to have solved your problem, but whether or not the mirror you're using is available, the command you posted won't work. You need to put the package name in quotes: install.packages("reshape2"), as you may have discovered. 

It's the object reshape2, which doesn't exist in your workspace, that triggers the error, not the presence or absence of the package reshape2 on the CRAN mirror you're using.

Best,
 John
