new_bmop: New bmop object

In gherardovarando/Rbmop: B-spline MoPs densities and conditional densities

Description

Constructor of bmop object. This fanction provide full control on the creation of a bmop object. It + is easier and safer to use the fitting functions like bmop_fit.

Usage

new_bmop(knots, order, ctrpoints = NULL, nk = FALSE)

Arguments

knots	list of numeric vector, knots of the B-spline basis
order	vector order of the B-spline for each variable, values will be recycled eventually
ctrpoints	array of control points
nk	logical, parameter used internally see details on how to use it

Details

The function create an object of class bmop, that is, a list with components

• order vector of orders

• knots list, every element of the list is the vector of knots in one dimension, knots are ordered but can be repeted.

• ctropoints An array of control points

If nk==FALSE (default method) the knots provided are sorted and the unique function is applied. Then the appropriate knots are computed, repeating the first and last knots many times as the order in the considered dimension, with this choice the bmop object represent a B-spline function regular up to the order-1 derivate in every dimension. If nk==TRUE the bmop object will be created without any check on the knots, use carefully this option as it could result in a wrong defined bmop object.

Value

An object of class bmop, a list with elements order, knots, ctrpoints,
