Sorry for the verbose example. I want to row bind two matrices, and all works
except I want the column labelled "row" to be sequential in the new matrix,
shown as "mat3" here, i.e. needs to be 1:6 and not 1:3 repeated twice. Any
suggestions?
Thanks

row ti counti
[1,] 1 7 9
[2,] 2 8 5
[3,] 3 7 9

row tj countj
[1,] 1 5 3
[2,] 2 6 8
[3,] 3 3 7
> mat3 <- rbind(mat1,mat2)
> mat3
row ti counti
[1,] 1 7 9
[2,] 2 8 5
[3,] 3 7 9
[4,] 1 5 3
[5,] 2 6 8
[6,] 3 3 7
