[BioC] increase memory size in R, problem reading 67 affy CEL files

i want to read in 67 CEL files (hgu133plus2 chips), but i get everytime the
error message: "Error: cannot allocate vector of size 709203KB"
i run R (version 2.0.1, bioconductor 1.5) on a linux workstation with 2 GB
physical RAM and 6 GB swap space... so there should not be any problem
regarding the memory installed on the system. is there a possibility to
increase the memory that can be allocated by R?
other question: the justRMA() function, does this function exactly the same as
ReadAffy() and then rma() ?

thanks for your help!
