I am having problem loading packages in the newest version of R (2.13.0) on my Mac. I have tried to install various packages (e.g. lawstat, Rcmdr, car) and load them using the Package Installer and Package Manager menu options but I get the follow error: > library(lawstat) Loading required package: mvtnorm Error: package 'mvtnorm' could not be loaded In addition: Warning message: In library(pkg, character.only = TRUE, logical.return = TRUE, lib.loc = lib.loc) : there is no package called 'mvtnorm' When I click on the box for loading lawstat in the Package Manager, it immediately reverts back to an unchecked box. I have tried to load mvtnorm and then load lawstat but I get the same error. Help? Thanks, Adrienne
Hi Adrienne,
I'm not familiar with your interface, but it sounds like R thinks the
package "mvtnorm" is not installed. You can see the packages
you've
installed with:
row.names(installed.packages())
Is "mvtnorm" in the output of that command? You could test with the
command,
"mvtnorm" %in% row.names(installed.packages())
If the result of the above command is FALSE, you can install it with:
install.packages("mvtnorm")
Best,
Ethan

This is a Mac issue. Use the R-SIG-Mac mailing list. 2. Assuming you are using the R Mac GUI, you use the Package Installer to install packages. If you want dependencies installed don't forget to check the Install dependencies checkbox in the lower right corner of the Package Installer window. Select lawstat and then click Install Selected. 3. Now you should be able to load.
