unexpected memory.limit on windows in embedded R
Dear All, I'm linking R from another application and embedding it as described in the R-exts manual, i.e. with initialization done via Rf_initEmbeddedR. While everything works the same as in standalone R for Linux, under Windows I found a difference in the default memory.limit, which is fixed to 2GB (both win32 and win64) - compared to a limit in standalone R of 3.5GB for win32 and 16GB on

Easy method to set user-mode virtual memory space in Windows Vista and 7
I thought I'd share this with the list since it appears to provide a quick fix to some memory problems, and I haven't see it discussed in relation to R. To reallocate virtual memory from kernel-mode to user-mode in 32-bit Vista or Windows 7 one can use the increaseuserva boot option value. See http://msdn.microsoft.com/en-us/library/aa906211.aspx On my 4GB Vista machine, R is now able to

Memory issues
Hi, I'm using R on Windows and upgraded the computer memory to 4GB, as R was telling me that it is out of memory (for making heatmaps). It still says that the maximum memory is 1024Mb, even if I increase it using memory.limit and memory.size. Is there a way to permanently increase R's memory quota to 4GB? Please help. Many thanks, -DS. [[alternative HTML version deleted]]

Memory Limits in Ubuntu Linux
I am an R user trying to get around the 2Gig memory limit in Windows, so here I am days later with a working Ubuntu, and R under Ubuntu. But - the memory problems seem worse than ever. R code that worked under windows fails, unable to allocate memory. Searching around the web, it appears that the problem may be the ability to find contguous memory for my big vectors, but a fresh boot of

maximizing available memory under windows XP
I have always been using ebitbin to set the 3GB switch in the windows binary, but version 2.2.1 has this set as default (which I verified using dumpbin). However, when I generate junk data to fill up my memory and read the memory usage using gc(), it seems that I am not getting as good results with 2.2.1 patched as I was with 2.2.0 after I edited the header. Under R 2.2.0 I was able to use over

How to verify using more than 2GB of memory
My machine has 4Gb of memory under WinXP Pro. Re-reading R for Windows FAQ 2.7 I discovered that I can use editbin to add the "/LARGEADDRESSAWARE" tag in the header without re-compiling, so that is what I did. I also check that it worked using dumpbin. I then edited my Boot.ini file to add the /3GB switch. Then I went to my R.0.0.1 patched that I modified as above and checked memory

R 64-bit memory.limit() is max of ?
Currently using R 2.92 Win XP Goal: scale up computing capacity for large datasets (1-5 million records) I realize under 32 bit versions of R the memory.limit is maxed at 4GB. Q: 1. What are the limits under 64 bit versions of R? Are those limits OS dependent? 2. Are there limits to the size of individual objects?? 3. Are there limits or problems in using functions such as lm(), glm(),

Difficulty Increasing R memory on Windows 32-Bit
I'm having difficulty increasing the memory R can access above 2Gb and wasn't able to resolve this from the R Windows FAQ. For reference, I'm running Windows XP, 32bit, Service Pack 2 on a machine with 4GB RAM. Following the FAQ, I set the --max-mem-size flag to 2800Mb. However, when I start R, I get the error: "WARNING --max-mem-size=2800M: too large and taken as 2047M."

running out of memory while running a VERY LARGE regression
I am running a VERY LARGE regression (many factors, many rows of data) using LM. I think I have my memory set as high as possible. ( I ran "memory.limit(size = 4000)") Is there anything I can do? ( FYI, I "think" I have removed all data I am not using, and I "think" I have only the data needed for the regression loaded.) Thanks.

RODBC, optimizing memory, "Error: cannot allocate vector of size 522 Kb".
I am using RODBC and "odbcConnect". I have successfully used odbcConnect to extract "modest" amounts of data from SQL. For convenience, (and maybe speed?) I wish, if possible, to extract larger amounts of data in a single query. (I am running R2.6.0 under a machine running Windows Small Business Server with 3mb of RAM. I run gc() prior to attempting the query. I have

64-bit OS, WINE and Memory (size) related question.
Having avoided them for some time now, based on compatibility concerns as I began to learn and use Linux full time, I?ve recently gotten the urge to start playing around with some 64-bit distro?s. The benefit of course is running more than the 4Gb (system-wide) limit imposed by a 32-bit OS. In my current system I only have 2Gb (2x1Gb) of RAM so I?m thinking of either adding 4Gb (2x2Gb) or even

Higher memory requirements for 64 bit?
I have a dual Xeon 3.2GHz XDMCP server serving out about 50 Gnome desktops to thin clients. I currently am running 32 bit with 4GB of memory. Performance is fine, normally, and the machine runs with about 3GB in swap. However, if a user app suddenly sucks up the maximum allowed rss and virtual or 256MB/process as specified by ulimit, the resulting swap drags the machine down to the point that

FC5 32-bit vs 64-bit
Hello, I am a biostats student and a newbie to R. I have a question about 32-bit vs. 64-bit. I am running FC5 on a AMD 3800+ with 2GB Ram. With 64-bit, I am running into some issues the stability of FC5. A friend suggested I ditch the 64-bit version of FC5 for the 32-bit. I do not currently have any pressing needs for the capabilities of the 64-bit OS. Before I reinstall the 32-bit

Out of memory crash on 64-bit Fedora
Greetings all, First of all, thanks to all of you for creating such a useful, powerful program. I regularly work with very large datasets (several GB) in R in 64-bit Fedora 8 (details below). I'm lucky to have 16GB RAM available. However if I am not careful and load too much into R's memory, I can crash the whole system. There does not seem to be a check in place that will stop R from

32 Bit vs. 64 Bit Linux Server installation
Hi Centos Users What are the advantages of 64 Bit and respective 32 Bit installation of Centos? With PAE 32 Bit installation can address huge amount of RAM. As a desktop system, I prefer 32 Bit installation because of teething troubles in 64 Bit Linux world. When would you choose 64 Bit and when 32 Bit? We are running mostly application and web services. Is this true that with 32 Bit

Allocated Memory Warnings in Vista 32 bit with 4 GB (PR#12560)
I see no bug here. R is telling you that you have insufficient memory available: see also ?"Memory-limits". See also rw-FAQ Q2.9. Note that we don't have a reproducible example and in particular have no idea of how many columns this data frame has. The 'R Data Import/Export' manual gives you many hints on how to do this more efficiently, and it is referenced from the

32-bit vs 64-bit CentOS on 64-bit hardware
I was asked this question today and frankly, I didn't know the answer. So I thought I'd post it here.... If you don't need to access greater than 4GB RAM, is there any benefit to running the 64-bit version of CentOS vs the 32-bit one? That's assuming, of course, that the target machine utilizes a 64-bit capable processor. I hadn't seen any noticeable difference, but I
