Details
Command-line flag --max-mem-size sets the maximum value of
obtainable memory (including a very small amount of housekeeping
overhead). This cannot exceed 3Gb on 32-bit Windows, and most versions of
Windows are limited to 2Gb. The minimum is currently 32Mb.
If 32-bit R is run on some 64-bit versions of Windows the maximum value of obtainable memory is just under 4GB.
Memory limits can only be increased.
Value
Size in Mb (1048576 bytes), rounded to 0.01 Mb for memory.size
and rounded down for memory.limit.
