fd2funData | R Documentation |
This function converts an object of class fd
(from
package fda) to an object of class funData
. It
heavily builds on the function eval.fd
from the
fda package. The fd
representation assumes a
basis representation for the observed functions and therefore
implicitly smoothes the data. In funData
objects, the data is
saved in 'raw' format.
