Re: [R] R.matlab memory use

Hi Henrik, Thanks for R.matlab and your reply. I cannot find any octave option to save an uncompressed MATLAB-format file. I have just downloaded Rcompression from what I believe is the official website so it should be current. I also think I have the current R version (at least, what is current

Re: [R] R.matlab memory use

Hi, I am using Octave; what does that save options do, more specifically, is compression taking place when saving that file? If compression is done, then the Rcompression package is utilized by R.matlab (otherwise not). BTW, you don't have to load Rcompression explicitly; R.matlab will do it

Hi Ben, Thanks for your reply. My data structure is about 2 x 2000 so one order of magnitude the one you tried. I have no problem saving and reading smaller data structures (even large ones, just not his large) between octave and R using octave's save -7 (which saves MATLAB v5 files) and

Re: [R] R.matlab memory use

Hi, The data set is indeed highly redundant, mostly zeros (which means I could use sparse matrices, but that's another issue). I have posted an octave ascii file here: http://dl.dropbox.com/u/4000198/freq.txt and a .mat file here: http://dl.dropbox.com/u/4000198/freq.mat    A few more

[R] R.matlab memory use

Hi, I am trying to load into R a MATLAB format file (actually, as saved by octave). The file is about 300kB but R complains with a memory allocation error: library(Rcompression) library(R.matlab) Loading required package: R.oo Loading required package: R.methodsS3 R.methodsS3 v1.2.0
