[R] How packages are set up

[Frank E Harrell Jr]

In trying to get more familiar with R I have two questions.

1. For large packages it would be slow to parse all R source
code for the package each time library() is issued.  
Yet I haven't found where a package's functions are stored 
in in .RData format.  Would someone please clarify this?

2. Have package developers found that it works best to
maintain packages locally using the same directory structure 
described in "Creating R Packages" in the "Writing R
Extensions" manual?
