6.1 Get source trees with branch lengths
Extra! Try it yourself.
chronograms <- rotl::studies_find_trees(property = "ot:branchLengthMode", value = "ot:time", verbose = TRUE, detailed = TRUE)
class(chronograms) names(chronograms)
We should be able to use
list_trees()
to get all trees matching our criteria.rotl:::list_trees(chronograms)
Except, it does not really work.
