Also, if you are using data.frame, consider switching to data.table as it allocates memory more efficiently. If you cannot do that the memory-mapping tools like package ff (or bigmemory as Sascha mentions) will help you build a new solution. All this is to take with a grain of salt as I am experimenting with R memory limits.

If the above cannot help, get a 64-bit machine with as much RAM as you can afford, and install 64-bit R.

I think you are wrong, but I might be mistaken. –tucson Jul 15 '14 at 12:04 1 I didn't mean that gc() doesn't work. 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. There 24 CEL files.

There are serval ways to dealwith that: -Free up memory along the way by removing tables you don't longer need - Work on a sample of the data. If you don't have 2.8Gb of continuous address space, you will see this error. –joran Jan 19 '12 at 3:49 does that mean there is nothing I can do MacDonald ♦ 40k • written 3.2 years ago by chittabrata mal • 50 0 3.2 years ago by James W. navigate to this website Usually always avoid this switch before reading all the caveats it implies for the OS and the programs. –Tensibai Sep 28 at 7:41 add a comment| Your Answer draft saved

How To Increase Memory Size In R yet again) Hello, I am facing the dreaded "Error: cannot allocate vector of size x Gb" and don't understand enough about R (or operating system) memory management to diagnose and solve
If that is not possible, then consider an alternative approach; perhaps do your simulations in batches with the n per batch much smaller than N. weblink From what I've read, I get the impression that it's not a matter of the available RAM per se, but of the available continuous address space.

You don't show what N is, but I suspect it is big, so try smaller N a number of times to give you N over-all. Unix The address-space limit is system-specific: 32-bit OSes imposes a limit of no more than 4Gb: it is often 3Gb. My overall impression is that SAS is more efficient with big datasets than R, but there are also exceptions, some special packages (see this tutorial for some info) and vibrant development navigate here There are other more niche things like don't use the function 'aggregate', etc.
There are also limits on individual objects. Bigmemory Package R Keep all other processes and objects in R to a minimum when you need to make objects of this size. Why are three-bladed helicopters relatively rare?
I printe the warnings using warnings() and got a set of messages saying: > warnings()1: In slot(from, what) Reached total allocation of 1535Mb: see help(memory.size) ...

There is good support in R (see Matrix package for e.g.) for sparse matrices.

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 Is there a word in Esperanto for "lightsaber"?

Stopping time, by speeding it up inside a bubble (Possibly Easy) Formal Language Question Can Klingons swim? It doesn't mean it needed to allocate 2.8Gb maximum.
By this point, all your available RAM is exhausted but you need more memory to continue and the OS is unable to make more RAM available to R. A loop should be almost as quick as lapply(), for most things. –Gavin Simpson Jun 7 '12 at 11:41 Your point is well taken. Run top in a shell whilst you run that R code and watch how R uses up memory until it hist a point where the extra 2.8Gb of address space is Allocation error I am receiving an allocation error while using different expression calls (MAS5 and LiWong).
Message "Error: cannot allocate vector of size 130.4 Mb" means that R can not get additional 130.4 Mb of RAM. Problems with "+" in grep If I am fat and unattractive, is it better to opt for a phone interview over a Skype interview? 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. It seems that rm() does not free up memory in R.
