Read the documentation: CHANGES or ?Memory.

  New command-line option --max-mem-size to set the maximum memory
  allocation: it has a minimum allowed value of 10M.  This is intended
  to catch attempts to allocate excessive amounts of memory which may
  cause other processes to run out of resources.  The default is the
  smaller of the amount of physical RAM in the machine and 256Mb.

You probably want to read the rest of the descriptions, and reading
documentation is always a good idea, so please do read the rest of the

There is a good reason for the numbers: the new malloc likes a contiguous
memory space, and R only reserves 256Mb initially (out of the 2Gb space on
non-server versions).  You can re-compile it to reserve more.
