This really isn't a question for the R-SIG-Mac list, since it's not OS specific; you might send this to R-Help. That's not a matrix -- just how the print statement works. E.g., if I print a long vector (1:1000) you'll see those little [1] boxes showing up on each line to indicate position. Note the result of is.matrix(x[1,1]) Incidentally, keep in mind that *everything* including scalars and matrices in R is a vector so "pure elements" are themselves vectors. Hope this

Assuming I have a matrix x like ? ? ? ?x <- array(1:20, dim=c(4,5)) and I try to access one of its elements like ? ? ? ?[1,1] result will be ? ? ? ?[1] 1 which looks like a (singleton) matrix itself. Can the pure elements be accessed? Thanks. hs
