[R] barplot

[syed gillani]

Hi all,

I have read in an epiinfo rec file with more than 100 variables and about
5500 rows. Among the variables are the following three: OB, a 0,1 coded
variable indicating the presence of obesity, GEN, a 1,2 coded variable
indicating gender and AGEGP, a variable  with values ranging from 1 to 11,
indicating agegroups.
How could I make a barplot showing male and female obese persons by age
groups?

Thanks
Basharat
