But you don't even tell us the operating system on your PC, normally a
characteristic of Windows users.
The amount of RAM pre-allocated to R under Windows can be increased, and
the help page you were referred to and the `R for Windows' FAQ (both of
which you have read?) tell you how.
But your `application' (about which you explain nothing) seems to be
needing excessive amounts of memory, and the best advice is to report that
to its programmer. Given how little RAM you have, you might want to
increase it to 1Gb or more.
