That is usually a bad idea.  If you have found a bug in the package, let 
the maintainers know about it.  If you want to add to it, write your own 
package that makes use of nlme.

If you start editing the package yourself, then quickly you'll end up 
being cut off from bug fixes and enhancements when the next version 
comes out.

For instructions on installing a source package, see the Writing R 
Extensions manual.
