looks like you've run out of memory mate, because that sure is a big matrix, you'd probably need 64 bit OS/CPU/R and loads of RAM.
see thread: http://www.nabble.com/Error-in-matrix:--too-many-elements-specified-td20457910.html I know there are some packages on cran which help with large datasets, but i haven't got around to using them myself (yet). from: http://cran.r-project.org/web/views/HighPerformanceComputing.html [quote start...] Large memory and out-of-memory data * The bigmemory package by Kane and Emerson permits storing large objects such as matrices in memory and uses external pointer objects to refer to them. This permits transparent access from R without bumping against R's internal memory limits. Several R processes on the same computer can also shared big memory objects. * A large number of database packages, and database-alike packages (such as sqldf by Grothendieck) are also of potential interest but not (yet?) reviewed here. [quote end.] Just for fun, i just tried (for the first time): > library(bigmemory) > big.matrix(nrow=80000, ncol=80000, type='double') but i ended up crashing out of R on my low spec windows XP uni laptop :D hope that helps a little, Tony Breyal On 25 Feb, 11:04, Corrado <ct...@york.ac.uk> wrote: > Dear friends, > > I have to use a very large matrix.
