It's because you've asked R to create an object of size 5 * 4 * 12488 * 1000 * 8 bytes, or 1905.5 MB, and R failed to get that much memory from the operating system. Andy
From: Gao Fay Hi there, When I run the following, why does it give a error like that?
res2<-array(0,c(5,4,12488,1000))
Error: cannot allocate vector of size 1951250 Kb Thank you for helping me. Fay
