Hi again the data represents a directed graph represented in a matrix e.g library(igraph) g <- forest.fire.game(10, fw.prob=0.3 , bw.factor=0.32/0.3, directed = TRUE)
m=get.adjacency(g , attr=NULL) print(m) ---------- many thanks and pardon me for multiple posts Ragia > Date: Mon, 6 Apr 2015 19:20:02 +0100 > From: ruipbarra...@sapo.pt > To: ragi...@hotmail.com; r-help@r-project.org > Subject: Re: [R] sort adjacency matrix > > Hello, > > You should have used ?dput to post your data example. > Since you haven't, I've made up one. > > set.seed(4795) > mat <- matrix(sample(0:1, 24, replace = TRUE), nrow = 6) > mat > > inx <- order(rowSums(mat), decreasing = TRUE) > mat[inx, ] > > > Hope this helps, > > Rui Barradas > > Em 06-04-2015 18:18, Ragia Ibrahim escreveu: > > Dear group > > i have the following matrix > > > > 1 . . 1 . . 1 . . . . > > 2 . . . . . . 1 . . . > > 3 1 . . . 1 . . 1 . 1 > > 4 . . . . . 1 . . . . > > 5 . . 1 . . . . . . 1 > > 6 1 . . 1 . . . . 1 . > > 7 . 1 . . . . . 1 . . > > 8 . . 1 . . . 1 . . 1 > > 9 . . . . . 1 . . . 1 > > 10 . . 1 . 1 . . 1 1 . > > > > I want to sort it according to ones in each row ascending (where max number > > of ones first) > > > > to be as follow > > > > 3 1 . . . 1 . . 1 . 1 > > 10 . . 1 . 1 . . 1 1 . > > 6 1 . . 1 . . . . 1 .8 . . 1 . . . 1 . . 11 . . 1 . . 1 . . . .5 . . 1 > > . . . . . . 17 . 1 . . . . . 1 . .9 . . . . . 1 . . . 12 . . . . . . 1 . > > . .4 . . . . . 1 . . . . > > > > how can I do this in R > > thanks in advance > > > > [[alternative HTML version deleted]] > > > > ______________________________________________ > > R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see > > https://stat.ethz.ch/mailman/listinfo/r-help > > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > > and provide commented, minimal, self-contained, reproducible code. > > [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
