[R] displaying a table in full vs. typing variable name

[Liaw, Andy]

Can you show how you know the output has only two columns?

My suspicion is that you are only seeing the `bottom' of the output, as in:

> x <- as.data.frame(matrix(rnorm(45), 5, 9))
> x
          V1         V2         V3          V4         V5           V6
V7

Why not use write.table() or even write(), instead of sink()?
