I think you want the following, assuming you defined your function g(): gValues = apply(S, 1, g); Sordered = S[order(gValues), ] Peter On Fri, Jan 21, 2011 at 11:38 AM, Francesco Petrogalli wrote: > Hi, > is there a R function that order a matrix according to some criteria > based on the rows(

[R] ordering a vector

Hi, is there a R function that order a matrix according to some criteria based on the rows(or cols) of that matrix? For example, let's say that my matrix S is composed by n rows S_1, S_2,.., S_n and that I compute some real value g_i=g(S_i) for each row. Then I want to order this set of g_i (from
