[R] Restoring an S object that was data-dumped

[Spencer Graves]

      1.  Could  you upgrade to the latest version of R (1.8.1)?  I 
don't know if it will help, but it might. 

      2.  I just used Notepad to open a data.dump file created in S-Plus 
6.2.  It started, "## Dump S Version 4 Dump ##".  How does your 
data.dump file begin? 

      3.  If you upgrade and can't solve the problem any other way, you 
could list out the "data.dump" code and step through it one line at a 
time until you identify the problem and a way to fix it -- at least in 
your case.  A "data.dump" file seems to be plain text, which means that 
it can be modified in a text editor, provided you know what to change. 

      hope this helps.  spencer graves
