How to set memory.limit in RStudio on Windows Vist

问题:

I am running RStudio 0.92.38 on Windows Vista x64. I have hard time to increase the memory limit to what I have (12GB) by using memory.limit, such as memory.limit(size=12000) for ~ 12 GB. I always get error:

memory.limit() [1] 3904 memory.limit(size=12000) [1] 3904 Warning message: In memory.size(size) : cannot decrease memory limit: ignored

Some related info:

version _
platform x86_64-pc-mingw32
arch x86_64
os mingw32
system x86_64, mingw32
status
major 2
minor 11.1

day 31
svn rev 52157
language R
version.string R version 2.11.1 (2010-05-31)

When I issued the same memory.limit() from Rgui.exe, I got:

memory.limit() [1] 12270

It seems RStudio is limiting the memory usage.

Any help?

Thanks. SP
