Evaluate a Spline Basis
Description
Evaluate a predefined spline basis at given values.

## S3 method for class 'bs' predict(object, newx, ...) ## S3 method for class 'ns' predict(object, newx, ...)
Arguments
object | the result of a call to |
newx | the |
... | Optional additional arguments. At present no additional arguments are used. |

for objects inheriting from classes "bs"
or "ns"
. See predict
for the general behavior of this function.
