[BioC] memory problem with Affy

[Phguardiol at aol.com]

Hi,
I am trying to use the Affy package on a windows XP PC with 512 Mo. I m 
loading 17 U133A chips.
I am trying to use widget and here is what I get:
Loading required package: tkWidgets
Loading required: tcltk
Error in firstlib(which.lib.loc, package) :
TCL_LIBRARY is not set
Error in eval(expr, envir, enclos) : tcl/tk package 'tcltk' not available -- 
forget about 'tkWidgets' !

When I dont use widget everything is about to be fine since in some 
operations, for instance when I try to use the hist function, I get this kind 
of message:
Error: cannot allocate vector of size 67328 Kb
In addition: Warning Message:
Reached total allocation of 511Mb: see help(memory.size)
The help does not help me that much, maybe because of my limited 
understanding of the process or of my poor english but maybe some of you can 
do better than the help file !?
Thanks
Philippe
