calc.Dss: Calculate the Dss statistic
In synDss: Recombination detection using synonymous distances

Description Usage Arguments Details Value Author(s) References See Also

This function calculates the Dss statistic using sliding windows.

1	calc.Dss(data, l, m, exhaustive=FALSE)

`data`	The sequence alignment, as a matrix of A,C,T,G characters
`l`	Step size for the sliding windows
`m`	Half-window size (total window size will be 2m)
`exhaustive`	logical; if TRUE, an exhaustive search over all possible topologies is performed at each step

Unless exhaustive=TRUE, this function uses bionj to quickly obtain the neighbor-joining tree before finding optimal branch lengths using least squares for each half-window; the branch length estimation is restricted to the topology obtained by the neighbor-joining algorithm.

A vector of numeric values, representing the Dss statistic at each window location.
