Re: [R] Problem loading packages in R 2.13.0 on Mac

[Ethan Brown]

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

 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

The error message would imply that the package mvtnorm is not installed.

1. 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.
