This function is a wrapper for PATHd8 and can be used for phylogenetic dating, especially of large trees
pathd8(phy, exec = "/Applications/PATHd8/PATHd8", seql, calibration)tree list of ultrametric trees returned from PATHd8 of class
phylo. First tree is PATHd8 chronogram, which is a calibrated
ultrametric tree. Second is a PATH tree, which is a ultrametric tree
without calibration.
An object of class phylo.
A character string giving the path to the PATHd8 program.
sequence length of alignment
A data frame with 4 columns and as many rows as calibration points. Columns are: taxon 1; taxon 2; one of c("minage", "maxage", "fixage"); age.
