similar to: R on os390

G'day R friends, I didn't get any replies on the main list so I thought I'd try with the experts. I was wondering if anyone's ported R to os390. If so, are the vsize and nsize limits the same as other platforms? I could really annoy those SAS guys then. thanks, John Strumila john.strumila@team.telstra.com

howdy gurus, I'm new and green and I was hoping for a tiny bit of your expertise. I'm running out of virtual memory (heap?) when summing using tapply. I've already used --vsize=90M on my hpux machine. (details below) Can I pre-sort or something to prevent my error? thanks, John Strumila john.strumila at corpmail.telstra.com.au > gc()["Vcells","total"] [1]

My group is working with datasets between 100 Mb and 1 GB in size, using multiple log ins. From the documentation, it appears that vsize is limited to 2^30-1, which tends to prove too restrictive for our use. When we drop that restriction (set vsize = NA) we end up hanging the server, which requires a restart. Is there any way to increase the memory limits on R while keeping our jobs from

howdy R friends, I'm new but I used to play with S+ a long time ago. Can someone please help me with how to approach this? I have some response time data I want to 'correlate' with other data. I believe queueing is involved so I need to prove somehow (F test?) that response ~ exponential(...) How do I go about this? I cant find exponential in 'nlm' or other functions.

Dear all, I don't get it: First of all, the help doesn't say what are the memory limits of R. Say, what's the max heap size for instance ???? Secondly, I invoke R with the following commands each time: rgui --vsize 30M --nsize 1000K rgui --vsize 30M --nsize 2000K rgui --vsize 30M --nsize 3000K rgui --vsize 30M --nsize 4000K I try to open a matrix 8000x8000 by issuing

HI,I would be interested if there is a release of Samba for Os390/Unix later that 1.9. (I have tried downloading the 'samba-latest.tar.gz' file from the mirror site,but as I cannot unzip/untar it,due to not having the 'gzip' program !). Therfore I am not sure how compatible it may or may not be with my Os390/Uss platform. Thanks for any help received in advance. John.

Hi everyone, I have a problem that some people may have already encountered but i did not find the solution yet. As I use R to simulate several arrays of data, my workspace is now 35Mb big and I cannot launch R with it. An "xdr real data read error occured" and R tells me to delete .RData or increase memory. I WON'T delete this file and changing the max-nsize to 40600k did not

Let me begin stating that I read all help files and faq's on the subject matter (there aren't more than about a dozen) but either did not find solutions or found them not to work. Here is the issue. I am trying to run a spatial regression on a medium-sized dataset. Part of the functions in the spdep package I use require me to allocate a vector of 1.1 Gb (mine is not a spatial SIG

Hello, I'm using a 64bit Linux with 16GB of RAM. I'd like to limit the memory that the R process can use so I'm trying to use --max-vsize switch. However, it is seems that I can't enforce a limit above 2GB. shlomo at hippo:~$ uname -a Linux hippo 2.6.24-16-generic #1 SMP Thu Apr 10 12:47:45 UTC 2008 x86_64 GNU/Linux This WORKS: -------------------- shlomo at hippo:~$ R

Hi Anyone have any idea on how to implement sftp in os390? Well .. using OpenSSH .. I've already installed SSL and SSH successfully .. I can do putty and scp .. but sftp is still a problem .. anyone has a guideline? thanks

Hi! I use 2 volumes to install Centos for OS390 (Address 120 and 121). All the installation process is ok, but when the linux says that i can reboot the system whitouth problems i dont't know the IPL addres to boot and the LOADPARM. Anyone can help me, please? Thanks

Dear R-users, I am trying to run some simulations in batch mode. In an older version of the program, I used rterm --vsize=100M --nsize=5000K --restore --save <input file> output file, however, in the new version R 2.2.0 , the parameters vsize and nsize are ignored. I can use the command memory.limit to increase memory, but I am not sure if this corresponds to vsize and nsize.

Hi list, I am analysing a large dataset using random coefficient (using nlme) and fixed effects (using lm function) models. I have problem with my R version 2. 2. 1 due to memory allocation difficulties. When I try to expand the memory I get the following error message. > R --min-vsize=10000000 --max-vsize=1000000000 --min-nsize=500 --max-nsize=10000000 Error: target of assignment expands

Hi, I have a few questions about how to handle large data sets in R. What is the size of the largest matrix that R can comfortably deal with? Is this size limit imposed by R's software, or is it a question of the machine that one runs on? How does one go about choosing reasonable values of vsize and nsize? I have a data set with about 1,000,000 rows, and 30

Hi, Is the following command used to increase the memory or any other command when a background R job is run? R --min-vsize=vl --max-vsize=vu --min-nsize=nl --max-nsize=nu --max-ppsize=N source: http://stat.ethz.ch/R-manual/R-patched/library/base/html/Memory.html Thx Carol [[alternative HTML version deleted]]

  R-devel, I am migrating from R.2.13.2 to R.2.15.1 and just realize that R command line options --max-nsize and --max-vsize are no longer supported along with the defunct of mem.limits(). To me, the function and options along with other two, --min-nsize and --min-vsize, are useful in allowing some explicit control of R memory usage. One benefit is that the setting of maximum boundary could

Hello R-community, It's been a week now that I am struggling with the implementation of a cox model in R. I have 80 cancer patients, so 80 time measurements and 80 relapse or no measurements (respective to censor, 1 if relapsed over the examined period, 0 if not). My microarray data contain around 18000 genes. So I have the expressions of 18000 genes in each of the 80 tumors (matrix

Dear Group I'm still trying to bring many data into R (see older postings). After solving some troubles with the database I do most of the work in MySQL. But still I could be nice to work on some data using R. Therefore I can use a dedicated Server with Gentoo Linux as OS hosting only R. This Server is a nice machine with two CPU and 4GB RAM which should do the job: Dual Intel XEON 3.06 GHz

Hi, I am not on this mailing list, but here is a terrible bug that has stopped me in my tracks. I am unable to remove observations from a data matrix. temp is the original matrix. Notice that there are 288 entries with a 104 in the first column. I attempt to remove these entries, but R does not do it. brad ACTUAL COMMANDS: > dim(temp) [1] 30528 11 > table(temp[,1]) 1 3 4
