memory use problem.

I having issues with my memory size in R for Windows.  I have implemented the
3gb switch for Windows 7 32 bit with 8gb of memory, only 4gb is available
for use due to 32 bit limitations.  512Mb is taken by the shared video card,
the memory limit is 2559mb yet I cannot use more than 1.5 gb of memory.  I
have searched eveywhere and cannot find any resolution to my issue.

memory.limit()

[1] 2559

memory.size()

[1] 399.47

a = aov(data$cv~(data$Lo+data$La+data$Mo+data$Co))

Error: cannot allocate vector of size 1.4 Gb

gc()

used  (Mb) gc trigger  (Mb) max used  (Mb)
Ncells   726003  19.4    2251281  60.2  1677683  44.8
Vcells 37249684 284.2   93398451 712.6 93388743 712.5

(1024 * 14) + 44.8 + 712.5

[1] 15093.3

Thank you,

Chris
