convert.sptab function

Convert geological ages in taxon-range tables as constructed by mk.sptab() for plotting alongside a time-calibrated phylogeny.

convert.sptab(sptab, tree = NULL, root.time = tree$root.time)

Arguments

• sptab: Taxon-range table to convert
• tree: Optional phylogenetic tree to draw root.time from
• root.time: Root time of the tree, used for converting ages

Returns

A data.frame() object in the format of the original taxon-range table, but with geological ages converted for plotting alongside the the phylogenetic tree.

Examples

data(archosauria)
data(tree_archosauria)
convert.sptab(archosauria$sptab_Coelophysoidea,tree_archosauria)
