Subject: R function for percentrank
In-Reply-To: <65cc7bdf0712010337o5844e1a3sfcb6984f93946267@mail.gmail.com>
I don't see one but that means nothing. I think you
can write such a function in a few minutes
Will something like this work or am I
missunderstanding what Excel's percentrank does ?
aa <- rnorm(25); aa # data vector
percentrank <- function(x) {
var <- sort(x)
p.rank <- 1:length(var)/length(var)*100
dd <- cbind(var,p.rank)
}
pr <- percentrank(aa); pr
