Dear Jonathan, It is not small, I passed the wrong information. I am running a geostatistic analysis with geoR that is computational intense. At the end my analysis I call the function krige.control and krige.conv. However, what call my attention is that I have a friend that was able to run the same code with his MAC 5 years old (OS 32 with 4 Gb of memory). Reading several email list I discovered that MAC has better library than repository in linux, but we can in increase the memory allocation in linux. I do not know how....
Below is the memory allocation for a MAC 32 of 4 Gb Ran. I know that it depends of the machine but it is far way better than in linux. Why? How to improve it in linux? Memory allocation in a laptop 4 years old MAC: > gc() used (Mb) gc trigger ( Mb) max used (Mb) Ncells 481875 25.8 984024 52.6 984024 52.6 Vcells 481512 3.7 140511341 1072.1 641928461 4897.6 Memory allocation in a new laptop Linux 4Gb 32 Ubuntu: >gc() used (Mb) gc trigger (Mb) max used (Mb) Ncells 170934 4.6 350000 9.4 350000 9.4 Vcells 195920 1.5 786432 6.0 781384 6.0 Thanks for your attention, Ricardo De: Jonathan P Daily <jda...@usgs.gov> Assunto: Re: [R] improve R memory under linux Para: "ricardo souza" <ricsouz...@yahoo.com.br> Cc: r-help@r-project.org, r-help-boun...@r-project.org Data: Sexta-feira, 5 de Novembro de 2010, 13:36 A "very small script" should fit just fine in an email: what are you trying to do? Likely, you are assigning many small variables in some loop. Even if you have 4GB of RAM available, if R assigns 3.99 GB of it and then then a call comes in to assign something of size .02, it will tell you it can't allocate an object of size .02. -------------------------------------- Jonathan P.

I am running a very small script and I always got the same error message: CAN NOT ALLOCATE A VECTOR OF SIZE 231.8 Mb. I have reading carefully the instruction in ?Memory. Using the function gc() I got very low numbers of memory (please sea below). I know that it has been posted several times at r-help (http://tolstoy.newcastle.edu.au/R/help/05/06/7565.html#7627qlink2). However I did not find yet the solution to improve my memory issue in Linux. Somebody cold please give some instruction how to improve my memory under linux? > gc() used (Mb) gc trigger (Mb) max used (Mb) Ncells 170934 4.6 350000 9.4 350000 9.4 Vcells 195920 1.5 786432 6.0 781384 6.0 INCREASING THE R MEMORY FOLLOWING THE INSTRUCTION IN ?Memory I started R with: R --min-vsize=10M --max-vsize=4G --min-nsize=500k --max-nsize=900M > gc() used (Mb) gc trigger (Mb) limit (Mb) max used (Mb) Ncells 130433 3.5 500000 13.4 25200 500000 13.4 Vcells 81138 0.7 1310720 10.0 NA 499143 3.9 It increased but not so much!
