Hi!

I have a data.frame, like this one:

> data
  0-100 100-250 250+
a     9      18   16
b    33      25   27
c    21      19   17
d    25      22   19
e    40      39   19
f    77      45   29

If I request a sample of 2, I have the following:

> sample(data, 2)
  0-100 250+
a     9   16
b    33   27
c    21   17
d    25   19
e    40   19
f    77   29

How can I request a sample from the rows???
