[R] memory.limit

[Francisco J. Zagmutt]

Hello Stephen,

I can confirm that I get the same behavior in my Windows machine.  Here 
is a summary:

 > memory.limit()
[1] 2046
 > memory.limit(2092)
Error in trunc(.Internal(memory.size(size))) :
   Non-numeric argument to mathematical function
 > memory.limit()
[1] 2092

As you described, the function reports an error but it indeed modified 
the memory allocation limit.  This must be somehow related to the 
modification to memory.limit() described in the release notes for 
Windows R version 2.9.0 
(http://cran.r-project.org/bin/windows/base/CHANGES.R-2.9.0)

 > version
                _

os             mingw32
system         i386, mingw32
status

minor          9.0
year           2009
month          04
day            17
svn rev        48333
language       R
version.string R version 2.9.0 (2009-04-17)

All: is this a bug or are we missing something?

Regards,

Francisco
