Simple operations like mean etc. can be applied
using lapply but not statistical functions.

--NONSENSE!

func <- function(x){
	##write any function you like
	z <- sin(x^2-2)+rnorm(length(x))
	lm(z~ seq(along=z))
	}
dat <- data.frame(a=1:5,b=rnorm(5))
lapply(dat,func)## could also have been inserted inline


Have you read "An Introduction to R" where these sorts of things are
discussed?
