[R] .First.lib doesn't appear to be running after calling lib rary()

[Liaw, Andy]

>From the R-exts manual:

====
The R subdirectory contains R code files. The code files to be installed
must start with a (lower or upper case) letter and have one of the
extensions .R, .S, .q, .r, or .s. We recommend using .R, as this extension
seems to be not used by any other software. It should be possible to read in
the files using source(), so R objects must be created by assignments. Note
that there need be no connection between the name of the file and the R
objects created by it. If necessary, one of these files (historically zzz.R)
should use library.dynam() inside .First.lib() to load compiled code. 
====

So the problem is the "." that the filename starts with.

HTH,
Andy
