[R] List or matrix of object

[jim holtman]

You probably need to review the Intro to R to understand indexing:

> f1 <- function(x) sqrt(x%*%x);
> f2 <- function(x) (2*x+1);
> L <- list()
> L[[1]] <- f1
> L[[2]] <- f2
> L  # contains the objects

[[1]]
function (x)
sqrt(x %*% x)

[[2]]
function (x)
(2 * x + 1)

> L[[1]](3)  # now call the functions in the list
     [,1]
[1,]    3
> L[[2]](42)
[1] 85
