...ave thought that R should have somewhere a function that took as arguments something like (data, breaks, what to do with the data in the bins). I surey could not find it trawling the R-help archives though. If such a function exists I'd be grateful to anyone pointing it out to me. Cheers, Fede -- Federico C. F.

...the same manner as the fist. How? I cannot turn the individual names in a numeric vairable with as.numeric(data1[,1]), because the two data frames are subset of different data, so the the factor levels are way off between the two. I think I need to actually use the names as a index. Cheers, Fede -- Federico C. F.

...matrix using rbind... nope! It seems I can read up to 500 lines in a *decent* time but nothing more. The machine is a 3 GHz P4 with HT and 512 MB RAM running R-1.8.1. Will I have to write a little a C program myself to handle this thing or am I missing something? Thanks in advance for your help, fede

Hi All, is there a way of predicting memory usage? I need to build an array of 86000 by 2500 numbers (or I might create a list of 2 by 2500 arrays 43000 long). How much memory should I expect to use/need? Cheers, Fede -- Federico C. F.
