fdParcheck {fda} | R Documentation |
Convert fd
or basisfd
Objects to fdPar
Objects
Description
If the input is an fd
object, default fdPar
parameters are
added to convert the object to an fdPar
object.
If a basisfd
object, it is first converted to an fd
object
with a nbasis
by ncurve
coefficient matrix of zeros,
and then converted to a fdPar
object.
Usage
fdParcheck(fdParobj, ncurve=NULL)
Arguments
fdParobj |
A |
ncurve |
The number of curves or functions for which the basis object is to be used in their representation. If missing, an error message is displayed and computation terminated. |
Details
The previous version of this function did not include the argument
ncurve
, and set up an fd
object with a square
matrix of zeros. This could cause an error in many of the
functions that called it.
Value
Returns a fdPar
object.
