\title{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{
  \item{rfu}{a numeric vector of signal value}
  \item{maxrfu}{signal values greater or equal to maxrfu are forced to NA}
}
\value{A single numeric value for the estimated baseline.}
