proj | R Documentation |
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
).
proj(fdobj, pca)
fdobj |
fd objects (list) of the splines construction containing coefficients, etc... This is produced by the function |
pca |
list containing the modes to project on, produced by the function |
pc
The principal components of the profiles stored in fdobj
projected on the modes contained in pca
.

bspl
for bsplines fit on T-S profiles, fpca
for functional principal component analysis of T-S profiles, reco
for reconstructing profiles with less modes.
