Projection of hydrographic profiles

Description

Projection of hydrographic profiles on a chosen basis (created with fpca). It is essential to locate a profile relatively to a climatology. The profiles to project must have the same basis than the modes to project on (i.e. same length of profile c(dmin,dmax) and same number of Bsplines nbasis).

Usage

proj(fdobj, pca)

Arguments

fdobj

fd objects (list) of the splines construction containing coefficients, etc... This is produced by the function bspl.

pca

list containing the modes to project on, produced by the function fpca.

Value

pc The principal components of the profiles stored in fdobj projected on the modes contained in pca.
