There is a slightly easier way to make your own functions available.

1. Set up a directory for your R configuration.  I use d:\r\mhp.  Copy 
.Rprofile, Rconsole, Rdevga there.

2. Set up a Windows environment variable R_USER pointing to that 
directory.  For example: R_USER=d:\r\mhp

The point of the preceding is to set R to load the same .Rprofile each 
time it starts.

3. Set up a separate directory for your own functions.  I use 
d:\r\mhp\mhpmisc.

4. Put your own functions in the directory from step 3.  Open R there.  
Source the functions.  Save the workspace as .Rdata.

5. In your .Rprofile file, add a line like this:

attach("d:/R/MHP/MHPmisc/.RData")

Now your functions will be available from every instance of R you start 
up.  If you have many functions, I have written an R script that 
searches the current directory for all of them, clears the workspace, 
sources them all, and saves the workspace.  Reply to me by email if you 
want a copy.

I have been told by Gurus that my method is too complicated, but I find 
it a lot simpler than creating a package.
