Function to convert phylogenies from the class 'phylo' to the class 'ggphy'
phylo2ggphy(phylo, tip.dates = NULL, branch.unit = NULL,
verbose = FALSE)
an object of the class "phylo"
a vector containing the sample dates of the tip in "Date" format, the dates must be ordered like the tips
the unit of the branch. Either "year", "month", "day" or "subst". If a time unit is provided, together with tip.dates, then the x-axis of the phylogeny will be in the Date format
if TRUE
