...results are matrixes of (50x14 to 1000x14) so they are small enough to work with them afterwards: create plots, or make some more analysis. So i wrote a function which do the analysis one file after another and keep only the results in a list. But after some about 2-4 files my R process uses about 1500MB and then the troubles begin. The R console terminates or prints the error that no more space can be allocated. So i have to do each file separate and save each result in a file and restart R after 2 processed files. And do that 3-5 times so that all files are processed, which is a bit anoying. I...

Hello, I am about to order a new workstation at my university that will be used for R (and other research related tasks). I would appreciate any feedback on the specifications of a very fast machine. The machine should run windows (XP probably better than vista). Which chip, memory size and specification, etc should I be looking for? Thanks, Ruud [[alternative HTML version deleted]]

Hi, I have 4 huge tables on which i want to do a PCA analysis and a kmean clustering. If i run each table individually i have no problems, but if i want to run it in a for loop i exceed the memory alocation after the second table, even if i save the results as a csv table and i clean up all the big objects with rm command. To me it seems that even if i don't have the objects anymore, the

Hi! I''m using the latest&greatest backgroundrb with rails 2.0.2 on ubuntu dapper. I''ve made an app that lets you run a query on several servers at once, which are selected at runtime. Therefore, for each server that is selected, I spawn a new worker and assign its work. After everything is completed, the workers are deleted. I often get this error:
