Dear R users,
I recently downloaded the library lme4a by 
svn checkout svn://svn.r-forge.r-project.org/svnroot/lme4. 
I tried to install the library lme4a by copying the downloaded document in
the location where all the R libraries are saved. 
When I try to load the library, I obtain the message

library(lme4a)
Error in library(lme4a) : 'lme4a' is not a valid installed package

R version 2.11.1 (2010-05-31)

You are copying the source package to the library where the compiled
packages are kept, which is why you are getting the error.  You will
need to install the package from the sources.  As a Linux user I find
the process straightforward.  Windows and Mac OS X users are often
taken aback by the complexity of the process.

What operating system are you using?
