Subject: Re: [R] Applying forecast functions to columns in a data frame
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?
