\title{Draw a tree}
\usage{
tree(
data,
root = data[[1]][[1]],
style = NULL,
width = console_width(),
trim = FALSE
)
}
\arguments{
\item{data}{Data frame that contains the tree structure.
The first column is an id, and the second column is a list column,
that contains the ids of the child nodes. The optional third column
may contain the text to print to annotate the node.}
\item{root}{The name of the root node.}
\item{style}{Optional box style list.}
\item{width}{Maximum width of the output. Defaults to the \code{width}
option, see \code{\link[base:options]{base::options()}}.}
\item{trim}{Whether to avoid traversing the same nodes multiple times.
If \code{TRUE} and \code{data} has a \code{trimmed} column, then that is used for
printing repeated nodes.}
}
\value{
Character vector, the lines of the tree drawing.
}
\description{
Draw a tree using box drawing characters. Unicode characters are
used if available. (Set the \code{cli.unicode} option if auto-detection
fails.)
}
\details{
A node might appear multiple times in the tree, or might not appear
at all.
