[R] Deleting observations - can't see the data after that

[jim holtman]

Can you give a reproducible sample of data.  Exactly what commands are
you executing when it doesn't print?  What does 'str(data)' show?

This works fine for me:

> x <- data.frame(a=1:5, b=1:5)
> x
  a b
1 1 1
2 2 2
3 3 3
4 4 4
5 5 5
> x <- x[-3,]
> x
  a b
1 1 1
2 2 2
4 4 4
5 5 5
> str(x)
'data.frame':   4 obs. of  2 variables:
 $ a: int  1 2 4 5
 $ b: int  1 2 4 5

Is there a way to get around that, either using a different deletion technique or another function?  print(data) and show(data) are not helping.

In this case I could guess at what is wrong and probably be correct, but I want to follow the clues as a learning exercise.  Once that is complete, I plan to plot everything with the deleted points emphasized.
