This is a wrapper around ape::plot.phylo() that makes several adjustments so plots agree more with accompanying kinship matrices.
In particular, tree is reversed on the y-axis to match matrix orientation, y-axis spacing is more padded for small trees, and an x-axis scale is always added.
The desired number of ticks in the x-axis (input to pretty(), see that for more details).
...
Additional parameters passed to ape::plot.phylo().
However, these parameters cannot be passed: x.lim (controlled via xmax), y.lim (a better default for small trees is passed and cannot be changed) and font (takes the value of par('font') instead of ape's default of 3 (italic)).

plot_popkin() can create multipanel figures including kinship matrices and trees (calling the present function in the process).
