noise: Noise Estimation

In rformassspectrometry/MsCoreUtils: Core Utils for Mass Spectrometry Data

Noise Estimation

Description

This functions estimate the noise in the data.

Usage

noise(x, y, method = c("MAD", "SuperSmoother"), ...)

Arguments

x	numeric, x values for noise estimation (e.g. mz)
y	numeric, y values for noise estimation (e.g. intensity)
method	character(1) used method. Currently MAD (median absolute deviation) and Friedman's SuperSmoother are supported.
...	further arguments passed to method.

Value

A numeric of the same length as x with the estimated noise.
