Basically I have 40 categories and each category has several hundred variables.
I want to calculate the average per category, that is variable *
frequency/Summation of frequencies. I want to do it for each category
separately. Since i have many categories i do not want to use the subset()
function 40 times. Is it possible to do it within a single data frame?
Really appreciate any help. Thank you.
