HiI have a data frame with rows specifying companies (codes are assigned to
companies) and columns specify months (monthly data). The data is based on male
(M) and female (F) information for each month. Following is an example of how
data looks like:
01 02 03 04001 na M M M001 M M M F002 M F F na003 M na na M003 F M M F003 F F
M M
na= no male/female.
Now, I want to firstly add rows with similar codes to see total number of Male
and Female in each month. Secondly, I need to calculate fraction of Female in
each month (F/ M+F) for these three companies.
Kindly guide me in this regard.
ThanksSaba
