2-dimentional Radial Spline

Description

2-dimentional radial spline generator used in cpglmm

Usage

sp2d(x1, x2, k = max(20, min(length(x1)/4, 150)), by = NULL, 
allPen = FALSE, varying = NULL, diag = FALSE, 
knots1 = quantile(x1, probs = 1:k/(k + 1)), 
knots2 = quantile(x1, probs = 1:k/(k + 1)))

Arguments

`x1`	the first covariate in the coordinate
`x2`	the second covariate in the coordinate
`k`	number of knots
`by`	not used. This is just for compatibility with `amer`.
`allPen`	not used. This is just for compatibility with `amer`.
`varying`	not used. This is just for compatibility with `amer`.
`diag`	not used. This is just for compatibility with `amer`.
`knots1`	vector of knot locations for the first covariate in the coordinate
`knots2`	vector of knot locations for the second covariate in the coordinate
