Dear all, apply(X, MARGIN, FUN, ...) returns an array of dimension c(n, dim(X)[MARGIN]) when FUN returns a vector of length n > 1.
Matrices and arrays are also vectors, so if FUN returns a matrix or an array, apply returns an array of dimension c(n, dim(X)[MARGIN]) as above. This is in accordance with the description of apply in the Blue Book, and also how Splus works (at least v6.0). I am curious: why was it decided not to return an array of dimension c(dim(result.of.FUN), dim(X)[MARGIN]) when FUN returns a matrix or an array? (This is not meant as criticism. I am sure there is a good reason; I just cannot see it.) -- Bjørn-Helge Mevik ______________________________________________ [EMAIL PROTECTED] mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
