Draws a phylogeny where x position of nodes and tips corresponds to value of a continuous trait variable, and y position corresponds to node depth (i.e. age).
Trait vector (same order as phy$tip.label, or with taxon names in names)
phy
phylo object
xaxt
x axis default type
underscore
if FALSE remove underscore from taxonomic names
show.names
if TRUE show taxon names across tips of phylogeny
show.xaxis.values
if TRUE show values for trait on x=axis
method
method for calculation of internal trait values. 'ML' = maximum likelihood method; 'pic' = independent contrasts method. pic option can be used when ML fails to converge or otherwise seems to fail to correctly reconstruct ancestral values
...
Additional arguments passed to plot
Value
Plots a traitgram, no values returned.
