Axis on Side of Phylogeny
This function adds a scaled axis on the side of a phylogeny plot.
axisPhylo(side = 1, root.time = NULL, backward = TRUE, ...)
- a numeric value specifying the side where the axis is plotted: 1: below, 2: left, 3: above, 4: right.
- the time assigned to the root node of the tree. By
default, this is taken from the
root.timeelement of the tree. If it is absent, this is determined from the next option.
- a logical value; if TRUE, the most distant tip from the root is considered as the origin of the time scale; if FALSE, this is the root node.
- further arguments to be passed to
tr <- rtree(30) ch <- rcoal(30) plot(ch) axisPhylo() plot(tr, "c", FALSE, direction = "u") axisPhylo(2, las = 1)
