Saving vector betwen function calls in sapply

[David Parkhurst <parkhurs@imap.iu.edu>]

I'm using splus Enterprise Developer Version 7.0.6  for Microsoft Windows

I'd like to call a function many times using sapply, with the result (a 
short vector) from call k being available to call k+1.  The results of 
the many calls also need to be saved into a matrix (or list?) in the 
usual way that sapply does.
How do I save the results of one call for use in the next call?  I think 
this has to do with frames, but I've never understood those.
Thanks for any help.
