Dear all, Starting from a recent version of R, the $ became "unusable" on atomic vectors, e.g. > x <- c(a=1,b=2) > x$a NULL Warning message: In x$a : $ operator is invalid for atomic vectors, returning NULL I can of course do > x['a'] - but that requires more typing (5 characters rather than 2). Apologies if I've missed a an announcement regarding this, but 1) Is there an alternative to the ['a'] and 2) Why was this change made? Regards Søren
