I could be wrong, but I think you did not provide information on your platform. Assuming it is Win32, it is an FAQ, please see: http://cran.r-project.org/bin/windows/base/rw-FAQ.html#There-seems-to-be-a-limit-on-the-memory-it-uses_0021 > >> x <- numeric( 200 / 0.025 * 1450 / 0.025) > Error: cannot allocate vector of size 3625000 Kb > You will hit memory limits rather quickly if you want to allocate not only one of your 3.6GB vectors - and this is neither the fault of R nor of Win32. Although I don't have a background in Computer Science, I think the physical limit to address memory on a 32bit system is 4GB. > 2^32/(1024*1024*1024) [1] 4 I hope this helps?
