Adam,
First, is possible 32bit XP use all your 4Gb?
Second, I think you say "gc" whem say "gs", so in my computer (Ubuntu
64bit with 4Gb):
> gc()
used (Mb) gc trigger (Mb) max used (Mb)
Ncells 188975 10.1 407500 21.8 350000 18.7
Vcells 169133 1.3 786432 6.0 786378 6.0
> gc(reset=T)
used (Mb) gc trigger (Mb) max used (Mb)
Ncells 188951 10.1 407500 21.8 188951 10.1
Vcells 168893 1.3 786432 6.0 168893 1.3
If you read gc help:
reset: logical; if 'TRUE' the values for maximum space used are
reset to the current values.
Other issue is options for rgui command.
Have a option "--max-mem-size" that you modify to expand you RAM
avaiable
