Reconstructs data curves as objects of class fd
using functional principal components
reconsCurves(data, PC)
a set of values of curves at discrete sampling points or
argument values. If the set is supplied as a matrix object, the rows must
correspond to argument values and columns to replications, and it will be
assumed that there is only one variable per observation. If
data
is a three-dimensional array, the first dimension
corresponds to argument values, the second to replications, and the
third to variables within replications.
