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)

Arguments

`rfu`	a numeric vector of signal value
`maxrfu`	signal values greater or equal to maxrfu are forced to NA

Value

A single numeric value for the estimated baseline.

Examples

data(JLO)
rfu <- JLO$Data$DATA.1
bl <- baselineabif(rfu)
plot(1:length(rfu), rfu, type = "l", 
  xlab = "Time [datapoint units]",
  ylab = "Signal [RFU]",
  main = "Example of baseline estimates")
abline(h = bl, col="red", lty = 2)
