Hello, I'm running into the following error: C:\Program Files\R\Rtools\bin\sh.exe: *** fatal error - couldn't allocate heap, Win32 error 487, base 0x7A0000, top 0x7b0000, reserve_size 61440, allocsize 65536, page_const 4096 I've re-installed Rtools and R (2.10.1) and followed all the prescriptions. I've checked that I only have a version of the gygwin dlls in my machine. Has anyone else found this problem? Any known memory conflicts with common software? Leo [[alternative HTML version deleted]]
