Derivative Order of a Savitzky-Golay Filter

A dials parameter for the derivative of step_savgol(): 0 (smoothing), 1 or 2. step_gap_derivative() uses it with the range 1 to 2.

Usage

savgol_derivative(range = c(0L, 2L), trans = NULL)

Arguments

range

The range of derivative orders. Default is 0 to 2.

trans

Not used.

Value

A dials quant_param object.
