A little utility function for dealing with the matrix-is-really-a-vector indexing duality. (Elemental (1,3) vs linear #4 indexing) E.g., x <- matrix(rnorm(9), 3, 3) which.min(x) # Not super helpful where.min <- function(x) arrayInd(which.min(x), dim(x), dimnames(x), T) where.min(x) # Perhaps better Cheers, Michael ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
