[R-SIG-Mac] G5 memory problems

[Jonathan Elsas]

Hello --

I'm trying to use the fastICA package on a G5 tower (dual 2GHz, 4Gig 
ram) and am continually running into memory allocation errors:

*** malloc: vm_allocate(size=844603392) failed (error code=3)
*** malloc[1272]: error: Can't allocate region
Error in fastICA(m, 10, method = "C", verbose = TRUE) :
         Calloc could not allocate (211149961 of 4) memory

I'm using R version 2.1.0

$ R --version
R 2.1.0 (2005-04-18).
...

and interfacing with R over TCP with Rserve v0.3-16 
(http://stats.math.uni-augsburg.de/Rserve/).

any advice on increasing the amount of memory R can allocate?  or is 
this a hard limit?
