Hi all,

I've got a simple contingency table produced with table(), and the upper and
lower quartiles (quantile25 and quantile75) for the same dataset.
Is there a function that tells me in which category does the value of the
quartile falls into?

for example:

tabsp <- table(fam$I[fam$I>0])

1 3 6
6 1 1

and for the cumulative frequency distribution

tabcum <- cumsum(tabsp)

1 3 6
6 7 8

so, If my lower quartile is "2", I can visually determine that it falls into
class/category "1" with 6 observations.  Is there a function that performs
this determination?

Thanks.
