[R] saving a global workspace?

[Vahid Pazirandeh]

hi all,

i can't call my custom R function.

i'm using R 1.3.1 on Solaris with the SJava pkg from www.omegahat.org.  This
package let's me call R functions from Java, and it works great.

i wrote a custom R function and saved it in the workspace.  in my homedir, i
noticed the file named .RData was created.  i also noticed my workspace is ONLY
restored if the current working dir (when i run R) is the one with that file in
it.

i finally wanted to move my command-line driven Java code to become a servlet. 
the servlet works fine if i call built-in R commands like "mean" and pass it
variables (i can even receive the results from the R call).  however, when i
attempt to call my saved function, R crashes (and also termintes my servlet
engine!).  

is there a way to save to a global workspace somehow?  i'm thinking the .RData
file can't be found, so my custom function isn't restored (though i checked the
current working dir just before the R call from Java, and i made sure to put
the .RData in that location).

any help would be awesome!

vahid
