Hey, Is it possible that R can calculate each options under each column and return a summary table?
Suppose I have a table like this: Gender Age Rate Female 0-10 Good Male 0-10 Good Female 11-20 Bad Male 11-20 Bad Male >20 N/A I want to have a summary table including the information that how many answers in each category, sth like this: X Gender Male 3 Female 2 N/A 0 X Age 0-10 2 11-20 2 >20 1 N/A 0 X Rate Good 2 Bad 2 N/A 1 So basically I want to calculate, in each column, how many people choose each answer, including N/A. I know I can do it in Excel in a very visualized way, but is there anyway to do it in R in a robust way if I have a fairly large dataset. Thanks!
