[R] partially sorting?

[jim holtman]

Is this what you want?  You may have to include other columns for
other levels of uniqueness:

> x
     [,1] [,2] [,3] [,4] [,5]
[1,] 1239   10   10   10   10
[2,] 1234   10   10   10   10
[3,] 1500   11   11   11   11
[4,] 1001   11   11   11   11
[5,] 1009   11   11   11   11
[6,] 1344   12   12   12   12
[7,] 1349   12   12   12   12
[8,] 1458   13   13   13   13
> x[order(x[,2], x[,1]),]
     [,1] [,2] [,3] [,4] [,5]
[1,] 1234   10   10   10   10
[2,] 1239   10   10   10   10
[3,] 1001   11   11   11   11
[4,] 1009   11   11   11   11
[5,] 1500   11   11   11   11
[6,] 1344   12   12   12   12
[7,] 1349   12   12   12   12
[8,] 1458   13   13   13   13
