Simply gooling for "writing ARFF file in R" gave the following as first hit, which is right on the WEKA page: Miscellaneous code [...] Function for reading ARFF files into the R statistical package (kindly provided by Dr Craig Struble).

I tried to compile R (current R-patched to be more precise) with gcc 3.5 by Apple (which will be probably shipped with Tiger) and here's how far I got: 1) compilation itself was fine except for one exception: ../../../../../../R-patched/src/library/stats/src/starma.c: In function `forkal': ../../../../../../R-patched/src/library/stats/src/starma.c:384: error: invalid lvalue in

I want R to read my Microsoft Access database or maybe even a Sybase database. I installed RODBC or at least thought I did.

I am currently using R 2.1.1 under Windows and I do not seem to be able to load the current versions of lme4/Matrix. I have run 'update.packages.' I understand this is still experimental software but I would like access to a working version. Thanks. Chuck R Output: > library(lme4) Loading required package: Matrix Error in lazyLoadDBfetch(key, datafile, compressed, envhook) :

Hello. I am not sure if this is a bug. I loaded into R a very large matrix, around 600,000 X 30 integers. My machine has 2G ram. After trying to write.table a modification of this matrix, R generated some sort of malloc error. Then, Error: vector memory exhausted (limit reached?) > q() Save workspace image? [y/n/c]: n *** malloc: vm_allocate(size=8421376) failed (error code=3) ***

R was working fine for a while. However, now after I get some data from the web and try to "write", "write.table" or "save.image", I get this error: Error in lazyLoadDBfetch(key, datafile, compressed, envhook) : file open failed I may have downloaded additional packages in between the time it worked, and now when it doesn't work, but other than that I cannot

Hi all, I am having memory allocation problem with my R 2.2.1 for Mac OS. The following is the error message that I get. I do not get this message if I break down the large dataset in to sub datasets. I think breaking up the dataset is not a sustainable solution in the long run. The data that I am analysing is essentially big, and it would be reasonable to do the analyis on the whole dataset

Dear all, I am having a memory problem when analyzing a rather large data set with nested factors in R. The model is of the form X~A*B*(C/D/F) A,B,C,D,F being the independent variables some of which are nested. The problem occurs when using aov but also when using glm or lme. In particular I get the following response, Error: cannot allocate vector of size 1.6 Gb R(311,0xa000d000) malloc: ***
