Presumably the function has already allocated a lot of memory (say, 150Mb)
before it tries to do the 41Mb allocation that triggers the error.  In
responding to the error R will unallocate all the memory that the function
had previously allocated.  You could confirm this by
which would make R report the currently used memory size with each garbage

To set the --max-mem-size option (or any other command line option), add
it to the 'Target' field in the 'Properties' for the shortcut to R.

"C:\Program Files\R\rw1030\bin\Rgui.exe" --max-mem-size=300M
