predictSpline {flexrsurv}

Generic method for prediction of spline function

Description

Predict a spline function by specifying its type, knots, degree and coefficients

Usage

  predictSpline (object, x, ...)
   
   ## Default S3 method:
predictSpline(object=c("b-spline", "tp-spline"), 
		x, knots, degree, keep.duplicates = FALSE, coef=1, ... )

Arguments

object

the type of spline to be predicted ("b-spline", the default, or "tp-spline")

x

Vector of values at wich to predict the spline function.

knots, degree

knots and degree of the relational model.

keep.duplicates

Should duplicate interior knots be kept or removed. Defaults is FALSE, which removes duplicate knots with a warning if duplicate interior knots are found.

coef

vector of coefficient of the spline function.

...

not used

Details

predictSpline .

Value

A vector the evaluated spline function with same length as x.

Examples

	
	predspline <- predictSpline("b-spline", 
		x= seq(from=-3, to = 3, by=.1), 
		coef = .5 * 1:5, 
		knots=c(-3,0,3), degree=3)
	plot(seq(from=-3, to = 3, by=.1), predspline)
