[R] rounding to whole number

[Sarah Goslee]

What about:

> ceiling(data[,2:3])
  A B
1 0 1
2 3 1
3 3 3
4 2 3

Note that ceiling is referenced in ?round

Thanks for the clear reproducible example.

But I wanted these cell to have 1 instead of 0. Another way, I could multiply by 10. But l did not want it because it affected my results later.
