8 \item{side}{a numeric value specifying the side where the axis is
9 plotted: 1: below, 2: left, 3: above, 4: right.}
10 \item{...}{further arguments to be passed to \code{axis}.}
13 This function adds a scaled axis on the side of a phylogeny plot.
16 The further arguments (\code{...}) are used to format the axis. They
17 may be \code{font}, \code{cex}, \code{col}, \code{las}, and so on (see
18 the help pages on \code{\link[graphics]{axis}} and
19 \code{\link[graphics]{par}}).
