baselineabif: Estimation of baseline value

Description

This function tries to estimate the baseline value for RFU data from capillary electrophoresis whith the heuristic that the most common value is the baseline.

Usage

baselineabif(rfu, maxrfu = 1000)

Value

A single numeric value for the estimated baseline.

Arguments

rfu

a numeric vector of signal value

maxrfu

signal values greater or equal to maxrfu are forced to NA
