I know that SAS at some "periods" keeps data (tables) on disk in special files, but I do not know the details of interfacing these files. No program should run out of memory until these are depleted. Which is also why bigmemory does not help, as randomForest requires a matrix object. –Benjamin Mar 3 '11 at 0:41 What do you mean by "only create the object

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 Gc() R See the OS/shell's help on commands such as limit or ulimit for how to impose limitations on the resources available to a single process.

I think I read somewhere that S+ does not hold all the data in RAM, which makes S+ slower than R. R Cannot Allocate Vector Of Size Linux
This is usually (but not always, see #5 below) because your OS has no more RAM to give to R.How to avoid this problem? MacDonald, M.S. Have a nice day! have a peek at these guys The c3.4xlarge instance has 30Gb of RAM, so yes it should be enough.
If you are allocating lots of different sized objects with no game plan, your RAM will begin to look like swiss cheese - lots of holes throughout and no order to 64 Bit R MacDonald ♦ 41k • written 3.3 years ago by chittabrata mal • 50 0 3.3 years ago by James W.

I need to have a matrix of the training data (up to 60 bands) and anywhere from 20,000 to 6,000,000 rows to feed to randomForest. Note that on a 32-bit build there may well be enough free memory available, but not a large enough contiguous block of address space into which to map it. Running 32-bit executables on a 64-bit OS will have similar limits: 64-bit executables will have an essentially infinite system-specific limit (e.g., 128Tb for Linux on x86_64 cpus). argument "intgroup" is missing in arrayQualityMetrics > source("http://bioconductor.org/biocLite.R") > biocLite("ArrayExpress") > library...
There is a bit of wasted computation from re-loading/re-computing the variables passed to the loop, but at least you can get around the memory issue. –Benjamin Mar 4 at 20:50 add How do I apply the process you show in the answer.
