x |
the positions where spline to be evaluated. |
xl |
lower intervall boundary where spline functions are relevant. |
xr |
upper intervall boundary where spline functions are relevant. |
spline.degree |
(polynomial) degree of the B-splines. |
nbasis |
number of basis functions used. |
comp |
Specify if only specific columns of the B-spline design matrix should be returned. Default is NULL and the whole B-spline design matrix is returned. |
