eval.fd {fda} | R Documentation |
Evaluate a functional data object at specified argument values, or evaluate a derivative or the result of applying a linear differential operator to the functional object.
eval.fd(evalarg, fd, Lfd=0)
evalarg |
A vector of argument values at which the functional data object is to be evaluated. |
fd |
A functional data object to be evaluated. |
Lfd |
Either a nonnegative integer or a linear differential operator object. If present, the derivative or the value of applying the operator is evaluated rather than the functions themselves. |
Returns an array of 2 or 3 dimensions containing the function values. The first dimension corresponds to the argument values in evalarg, the second to replications, and the third if present to functions.
