add.scale.bar

a numeric value giving the length of the scale bar. If none
    is supplied (the default), a value is calculated from the data.

This function adds a horizontal bar giving the scale of the branch
  lengths to a plot of a phylogenetic tree on the current graphical
  device.

hplot

Ape provides functions for reading, writing, plotting,
  and manipulating phylogenetic trees, analyses of comparative data
  in a phylogenetic framework, analyses of diversification and
  macroevolution, computing distances from allelic and nucleotide
  data, reading nucleotide sequences, and several tools such as
  Mantel's test, computation of minimum spanning tree, the population
  parameter theta based on various approaches, generalized skyline plots,
  estimation of absolute evolutionary rates and clock-like
  trees using non-parametric rate smoothing, conversion of APE trees
  to and from hclust objects and for classifying genes in trees using
  the Klastorin-Misawa-Tajima approach.
