R help - Jul 2008 - Saving a workspace with "extras"?

Hi everyone,

I hope there's a simple way to achieve what I want, but I haven't  
found the way.

I do microarray analysis using R and a number of packages as well as  
some functions created my myself.
When I save the workspace, it saves all the data structures, that's  
great... But when I click (I'm on Windows XP, if it matters) on teh  
resulting .RData file, I have to reload the functions I made, as well  
as the relevant packages. It is not really a big deal, but sometimes I  
want to give a colleague something I'm working on, and it would be a  
lot easier to just give the .RData file, without adding the extras.  
Especially when it comes to my own functions. I was hoping they'd be  
saved, because I see them listed after 'ls()' but they're not.

I'm starting to suspect that this is another reason why people build  
packages... but it seems a bit involved, especially in Windows. I was  
shown how to do it in Linux and it wasn't painful, but in Windows...  
ouch. Tried and failed repeatedly. Gave up.

Any comments appreciated!

Jose

Functions you've loaded using source() should be saved.

For loading packages automatically, create a function called
.First and save it in that workspace. Anything in that function
will be carried out when the workspace is loaded.
