You can't get this unless the package was installed with 
R_KEEP_PKG_SOURCE.  What you see in the console is *not* the original, 
it's a deparsed version of it.

To get the original, download the source to the package, and look in the 
R subdirectory.  If it's a base package, the package sources are online at

https://svn.r-project.org/R/trunk/src/library

This is the development trunk; different released versions will be in 
different subdirs below /R, e.g. 2.10.1 will be in

https://svn.r-project.org/R/tags/R-2-10-1/src/library/
