\title{Compute pairwise taxonomic distances for a set of taxa}
\usage{
distance_matrix(taxa, verbose = FALSE, progress = TRUE)
}
\arguments{
\item{taxa}{A character vector of taxon names.}

\item{verbose}{Logical. If \code{TRUE}, prints progress for each pair.
Default \code{FALSE}.}

\item{progress}{Logical. If \code{TRUE}, shows a progress bar. Default \code{TRUE}.}
}
\value{
A symmetric numeric matrix of class \code{"dist"} containing pairwise
distances. Row and column names are set to the input taxon names.
Taxa that could not be found are included with \code{NA} distances.
}
\description{
Given a vector of taxon names, computes all pairwise phylogenetic distances
and returns a symmetric distance matrix. Lineages are cached after first
retrieval to minimise redundant network requests.
