x |
A numeric vector representing the intensity values of a spectrum. |
process |
A character string denoting the name of the
process to register with the (embedded) event history object of the input
after processing the input data.

Since this function estimates the baseline of a spectrum as a monotone minimum, it works only if the portion before the maximum of the saturation period has been removed from the spectrum.
A vector representing the estimated monotonically decreasing baseline.
