[R] approximating matrix columns

[Rui Barradas]

Hello,

Try

apply(mat, 2, approx, method=”linear”, n=365)

This reads "apply to each column (dimension = 2) of mat the function 
approx with extra args method and n".

Three notes.
1. Your data does NOT have three list, it IS one list with three vectors.
2. 'matrix' is a function so choose something else as a name. Above I've 
chosen 'mat'.
3. Bert is obviously right. You are wrong in not following simple 
posting instructions. And in not even bothering to quote his post.
