making custom function compute/return multiple items
Hello, I'm relatively new to R. I've read the intro guide, but I
can't quite figure out how to:
I have a function:
Jcost <- function (theta, in, out) {
a <- output - input %*% theta
1/2 * t(a) %*% a
}
where
"theta" is a 2x1 matrix
"in" is a 20x2 matrix
"out" is a 20x1 matrix
return value is a scaler
This works well when I only want to compute given 1 theta matrix. How
do I...
