\title{Internal: create character matrix out of allele list}
\description{
For use in \code{\link{alleleinit}}.
Creates a matrix of characters in which there are two rows for
every individual corresponding to the two alleles in every locus
(column) out of a list of lists, such as required by
\code{\link{alleledist}}.
}
\usage{
build.charmatrix(allelelist,n.individuals,n.variables)
}
%- maybe also `usage' for other objects documented here.
\arguments{
\item{allelelist}{A list of lists. In the "outer" list, there are
\code{n.variables} lists, one for each locus. In the "inner" list, for every
individual there is a vector of two codes (typically characters, see
\code{\link{alleleinit}}) for the two alleles in that locus.}
\item{n.individuals}{integer. Number of individuals.}
\item{n.variables}{integer. Number of loci.}
}
\value{
A matrix of characters in which there are two rows for
every individual corresponding to the two alleles in every locus
(column).
