Dear all, i have a question as regards to the read.table /table command: I read in the following file: Method1 23 Method2 12 Method3 43 Method4 76 Method1 2 Method3 4 If i use the "table" command I get the following matrix: V2 V1 2 4 12 23 43 76 Method1 1 0 0 1 0 0 Method2 0 0 1 0 0 0 Method3 0 1 0 0 1 0 Method4 0 0 0 0 0 1 Is it possible that R groups my values, to get an matrix which looks nearly like this: V1 Method1 23 2 Method2 12 0 Method3 43 4 Method4 76 0 Some ideas? Thanks in advance Cheers Sebastian
