Thank you very much for your help!!
Now, it runs without any problem.
Is it going to be fixed in the next release?
Thanks again,

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.
