Daniel, I can't help much with the segfault, but if you want someone to help you need to provide a minimum reproducible example. In this case you have the code, but not the data - leaving me wondering :
is this dataset so huge that most computers would run out of capacity? does it happen with a subset of the data? (even just a few rows... one row?) does it happen with a hist of anything - what does hist(rnorm(1e4)) give you ? is there a column called foo in the file? is there an out of range value in the csv file? I would suggest you supply the data (or at least as much as is required to reproduce the error), and also the output of sessionInfo() As a R newbie, you might also want to have a look at : http://www.r-project.org/posting-guide.html http://www.catb.org/~esr/faqs/smart-questions.html I hope someone can help you more than I! cheers Ben On 07/12/2011, at 9:34 PM, Daniel Serodio (lists) wrote: > I'm a complete R newbie.
