I would like to make a couple of small suggestions regarding rank. All of these can be done now but with the the indicated additions, one could have clearer code: PRESERVE NAMES It would be nice if rank(v) preserved the names of vector v. Currently you have to do this: rv <- rank(v); names(rv) <- names(v) which seems unnecessarily elaborate. Note that when you rank some items you often want to know which items were ranked where so its natural that you would want to preserve the names. TIED RANKS It would be nice if there were an option to control whether tied ranks are averaged or not. Currently they are averaged. As a workaround, one can create a function to do this: myrank <- function(x) { y <- order(order(x)) names(y) <- names(x) return(y) } but it would be tidier if the option were available within rank itself. ASCENDING OR DESCENDING It would be nice if one could specify whether the rank was to be computed in ascending or descending order. rank(-x) (in the case of numeric data) and rank(-rank(x)) with numeric or character work but an option would be more direct. -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
