I recently fixed a minor bug that could have >>>> symptoms like this. Under most 64-bit versions of Windows the limit for a 32-bit build of R is 4Gb: for the oldest ones it is 2Gb. Note that on a 32-bit OS there may well be enough free memory available, but not a large enough contiguous block of address space into which to map it. PS: Closing other applications that are not needed may also help to free up memory. #2 | Posted 16 months ago Permalink Frank Inklaar Posts 17 | Votes 2 Joined 1

You can't increase memory indefinitely, eventually you'll run out. R looks for *contiguous* bits of RAM to place any new object. Error messages of the type “Cannot allocate vector of size...” is saying that R cannot find a contiguous bit of RAM that is that large enough for whatever object it was https://stat.ethz.ch/pipermail/r-help/2008-January/151380.html My main difficulty is that I get to a certain point in my script and R can't allocate 200-300 Mb for an object...

Each new matrix can’t fit inside the RAM footprint of the old one, so R has to find a *new* bit of contiguous RAM for the newly enlarged matrix.

It is not normally possible to allocate as much as 2Gb to a single vector in a 32-bit build of R even on 64-bit Windows because of preallocations by Windows in Why is this true (that formula semantics are highly inefficient)? –Josh Hemann Oct 28 '11 at 14:46 1 In short, it usually works by calling a series of not-too-fast functions One of the most vexing issues in R is memory.
