[R] functions and multiple levels

Hi, I am trying to write a function; I want to subtract the mean of each class in level 2 from the mean of each class in level 1 and square the answer, eg. level.1 level.2 observation 1 1 0.5 1 1 0.2 1

Re: [R] functions and multiple levels

Hi Chris, Try ?ave will help you. Anyway, I guess you are computing a statistic. strs <- " level.1 level.2 observation 1 1 0.5 1 1 0.2 1 2 0.6 1 2 0
