[R] Which "apply" function to use?

Dear All, I have a problem which *should* be pretty straightforward to resolve - but I can't work out how! I have a list of 3 coefficient estimates for 4 different datasets: Coefs<-list(c(1,0.6,0.5),c(0.98,0.65,0.4),c(1.05,0.55,0.45),c(0.99,0.50,0.47)) All I want to do is take the sum (or mean
