I apologize for my constant questions but I am new to R and trying to
gain an appreciation for its capabilities. The following task is easy
in Excel and I was hoping somebody could give me a quick explanation
for how it can be acheived in R so I can avoid having to switch
between the two applications.

I would like to see compute the mean Height, Weight, and Ratio as well as their variances for each of the years under Year Drafted(1980-2000). What is the most efficient way of doing this?

Thank you.
