Hi, as a newcomer to R i have what probably is a very simple issue but i have been to solve it for hours: all i want to know is how to arrange a set of numbers in size order without putting them in a table. just arranging them from for e.g. 2,1,3,5,4 into 1,2,3,4,5 - it must be simple but i cant find how to do it anywhere thanksdan _________________________________________________________________ [[elided Hotmail spam]] [[alternative HTML version deleted]]
Welcome to R! I don't quite know what you mean by size order. But if you have five numbers: a <- c(2, 1, 3, 5, 4) then sort(a) will do what you want? HTH!
