what should your matrix look like? do you mean something like this? p1=c(1,1,2,2) p2=c(1,2,1,2) d=c(0,4,4,0)
cbind(p1,p2,d) d2=matrix(d,length(d)/2,length(d)/2) d2 Cheers, Daniel ------------------------- cuncta stricte discussurus ------------------------- -----Ursprüngliche Nachricht----- Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Im Auftrag von skinny c Gesendet: Sunday, November 09, 2008 7:11 PM An: r-help@r-project.org Betreff: [R] how to convert indvidual pairwise distances to matrix Hello, I am trying to convert list of pairwise distances to a distance matrix for spatial analysis (kriging). For instance, I have something like this for each pair pf points, and I want to convert it to a matrix: point1 point2 distance 1 1 0 1 2 4 2 2 0 2 1 4 Please let me know if there is a function or method that can do this. Thanks, Christy [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list 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. ______________________________________________ R-help@r-project.org mailing list 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.
