Good day! 

Problems fixed. Resolutions:

require(pracma, warn.conflicts = FALSE) after library(pracma).

The code is now working. (The examples in the link
show the sample code for the function, but not the prerequisites. I've found
the prerequisites, so thank you very much!)

Why don't you just try the function whittaker from the pracma R package?
There is an example which should be adequate for finding out what to do.
