Get aligned sequences from the Fish Tree of Life

Retrieves an aligned sequence via the Fish Tree of Life API. If neither `species` nor `rank` are specified, returns the entire sequence matrix.

fishtree_alignment(species, rank, split = FALSE)

Arguments

species

(Optionally) subset the results based on a vector of species names.
rank

(Optionally) subset the results based on the supplied taxonomic rank.
split

Splits the output into a list by gene locus.

Value

An object of class `"DNAbin"`, or a named list of the same if `split = TRUE``
