Lalitha,
Try something like
with(data, table(cut(age, n), member_FLAG))
where data is a data frame with columns named age and member_FLAG and n is
the number of age categories (bins) you want. This will give you the
number of Ys and Ns in each bin, that you will need to convert to
percentages.
Also, you might want to check the help pages for table and cut.
Cheers,
Andy

[R] Query about using table

Hi
I have data of the following form
ID age member_FLAG
1 25 Y
2 36.75 N
3 75.5 N
.........
.........
I want to get a histogram of this data showing
distribution of member_flag in each age-bin i.e. how
many values in each age bin have a member_flag of 'Y'
and how many have 'N'.
I was able to do the same using barplot2.
However I also need similar information in a tabular
form using percentages.
i.e in each age bin, what is the PERCENTAGE of IDs
with a member_flag of 'Y'
I am trying to work with table for the same, but would
appreciate some guidance regarding the above.
Thanks
Lalitha
