I've a linux system with 2Gb of memory which is not enough for reading a 446Mb netcdf file using ncdf: library(ncdf) ncold <- open.ncdf("gridone.grd") Error: cannot allocate vector of size 1822753 Kb When I look at the free memory in my system I can see that none of the Swap space is being used by R. I am a newbie in linux and R, I've read the Memory help pages but still have some questions: can I use the swap space in R to solve my problem of lack of memory? if not, are there any ways to read the data apart from buying more RAM? Thanks, M
Hi Manuel, Look at your memory.limit() and run R with '--mem-max=' option Try also to use the simpler netCDF library Antonio> -----Mensaje original----- > De: r-help-bounces at stat.math.ethz.ch > [mailto:r-help-bounces at stat.math.ethz.ch]En nombre de Manuel Gutierrez > Enviado el: viernes, 21 de enero de 2005 10:03 > Para: r-help at stat.math.ethz.ch > Asunto: [R] memory and swap space in ncdf > > > I've a linux system with 2Gb of memory which is not > enough for reading a 446Mb netcdf file using ncdf: > library(ncdf) > ncold <- open.ncdf("gridone.grd") > Error: cannot allocate vector of size 1822753 Kb > > When I look at the free memory in my system I can see > that none of the Swap space is being used by R. > I am a newbie in linux and R, I've read the Memory > help pages but still have some questions: > can I use the swap space in R to solve my problem of > lack of memory? > if not, are there any ways to read the data apart from > buying more RAM? > Thanks, > M > > ______________________________________________ > R-help at stat.math.ethz.ch mailing list > stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide!R-project.org/posting-guide.html -- No virus found in this incoming message.
