Re: [R] add a special column to a matrix
Hi Lida, I think what you want is: mat1-read.table(text=abc d fg1:23 dfgv 5 pt10:18 tgtgh 1 wq 15:123oiljk 6 fg 9:1323ass 4 yr 12:123kjjlk 5,header=TRUE) mat2-read.table(text=b q 1:23 0 10:18 1 14:4552 15:1232 9:13232 12:1231 5:15480,header=TRUE) merge(mat1,mat2,by=b) You don't seem to have a column name for the first column in mat2, so I have added one. If it is different from mat1, you will have to use a slightly different b argument.
