I've just started digging into Andreas's old report: > a <- array(0,c(2,2,2)); > dimnames(a)<-list(hansi=1:2, pepi=c("a","b"), karli=3:4) > dimnames(a[,,1]) # losing component names [[1]] [1] "1" "2" [[2]] [1] "a" "b" Now, this would be fairly easily fixed (I think) which would also make it compatible with S3.

...;,"from") ) res <-apply( y, "to", sum) -- This makes the array much easier to handle than having to keep track which dimension currently means what. For aperm and apply, the change seems very simple - one new function, and an additional line in each. ---------- dimnum.from.dimnamename <- function(A, dimensions) { if( is.character(dimensions) ) { n <- names(dimnames(A)) if( !is.null(n) ) { dimnum <- seq( along=n) names(dimnum) <- n dimensions <- dimnum[dimensions] } } dimensions } aperm <- function (a, perm, resi...
