Hi,
If you can formulate your question it in terms of actual problem you have with data.frame it would be easier to answer.
for the time being check subset() if it is what you want.

Hi all,
I'd like to know, if I can solve this with a shorter command:
a <- rnorm(100)
which(a > -0.5 & a < 0.5)
# would give me all indices of numbers greater than -0.5 and smaller
than +0.5
I have something similar with a dataframe and it produces sometimes
quite long
commands...
I'd like to have something like:
which(within.interval(a, -0.5, 0.5))
Is there anything I could use for this purpose?
Antje
