[Bioc-devel] Loading a file for vignette

I would like to make a vignette that will instruct the user to load a file 
from a package distribution using one of the packages R functions.  The file 
is not a .txt file (or any of the other file types that should be in the data 
directory of a package).  Of course, the vignette needs to build and I would 
like to have those commands be the same as those used by the user.  I have 
looked around a bit and the packages that I have found do a simple 
load(somedata) where somedata is an R data file.  Is there a way to start 
directly from the original file, or am I better off creating the R object and 
loading it and simply telling the user how I created it?  This is a VERY 
small point, but I'm curious.

Thanks,
Sean
