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

> colnm1 <- c("row","ti","counti")
> colnm2 <- c("row","tj","countj")
> mat1 <- matrix(c(1,7,9,2,8,5,3,7,9),byrow=T,nrow=3)
> colnames(mat1) <- colnm1
> mat1
     row ti counti
[1,]   1  7      9
[2,]   2  8      5
[3,]   3  7      9
> mat2 <- matrix(c(1,5,3,2,6,8,3,3,7),byrow=T,nrow=3)
> colnames(mat2) <- colnm2
> mat2
     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
