I am having trouble calling the lmer function in the {Matrix} package. I first installed and loaded {Matrix} as follows:
> install.packages("Matrix") > library(Matrix) The package loaded successfully, however when I attempted to call lmer, I received the following message: Error: could not find function "lmer" I also tried: < ?lmer which produced no search results. I have attempted these actions in both MacOSx R Versions 2.4.1 and 2.5.0. I have also tried this in Version 2.5.1. beta on a Windows machine. Thanks in advance for any suggestions.
