\title{Change map function for a genetic map}
\description{
Convert a genetic map from using one map function to another.
}
\usage{
\method{convert}{map}(object, old.map.function=c("haldane", "kosambi", "c-f", "morgan"),
new.map.function=c("haldane", "kosambi", "c-f", "morgan"), \dots)
}
\arguments{
\item{object}{A genetic map object, of class \code{"map"}: A list whose
components are vectors of marker locations.}
\item{old.map.function}{The map function used in forming the map in
\code{object}.}
\item{new.map.function}{The new map function to be used.}
\item{\dots}{Ignored at this point.}
}
\value{
The same as the input, but with inter-marker distances changed to
reflect a different map function.
}
\details{
The location of the first marker on each chromosome is left
unchanged. Inter-marker distances are converted to recombination
fractions with the inverse of the \code{old.map.function}, and then
back to distances with the \code{new.map.function}.
