Hello John, Thank you for your prompt reply!
Unfortunately, I get the following message when trying to download the "effects" package from R-forge (and allEffects() doesn't work): Warning: unable to access index for repository > http://R-Forge.R-project.org/bin/macosx/mavericks/contrib/3.1 > package ‘effects’ is available as a source package but not as a binary > Warning message: > package ‘effects’ is not available (for R version 3.1.2) I don't think I have ever downloaded a packed from R-Forge before, so I am unsure of how to resolve this. Words of wisdom?
