It is trying to allocate a single memory block of size over 2^31-1 bytes. R internally uses ints for sizes of vectors and that is a limit (see help("Memory-limits") ). However, it is intended that on 64-bit systems that there is a limit here of 8*(2^31-1) but there was a typo. Please change line 1534 of src/main/memory.c to #if SIZEOF_LONG > 4 and re-compile. -- Brian D.
