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.
