smooth.construct.fpc.smooth.spec: Basis constructor for FPC terms

Description

Basis constructor for FPC terms

Usage

## S3 method for class 'fpc.smooth.spec':
smooth.construct(object, data, knots)

Arguments

object

a fpc.smooth.spec object, usually generated by a term s(x, bs="fpc"); see Details.

data

a list containing the data (including any by variable) required by this term, with names corresponding to object$term (and object$by). Only the first element of this list is used.

knots

not used, but required by the generic smooth.construct.

Value

• An object of class "fpc.smooth". In addtional to the elements listed in smooth.construct, the object will contain
• sm
  the smooth that is fit in order to generate the basis matrix over object$term
• V.A
  the matrix of principal components

Details

object must contain an xt element. This is a list that can contain the following elements: [object Object],[object Object],[object Object],[object Object],[object Object],[object Object] Any additional options for the pre-smoothing basis (e.g. k, m, etc.) can be supplied in the corresponding elements of object.
