Re: [R] cut out single lines out of matrix

Hi I am a bit curious why one shall do such a twisted construction. Accessing list is basically the same as accessing corresponding matrix row, you only need to remember drop=FALSE option. Regards Petr r-help-boun...@r-project.org napsal dne 17.03.2010 00:58:54: Here is a way of creating a

Hey dear users I'm trying to kind of split my matrix which looks as follows: dim(out) [1] 30 12 What I finally want is each line as it's own matrix which I can handle then separately. Like, say: out1- [1,] out2-[2,] .. Would you do that with a for() loop or does exist an other

Re: [R] cut out single lines out of matrix
