Apply a function to the subtaxa for each taxon. This is similar
to using subtaxa() with lapply() or sapply().
obj$subtaxa_apply(func, subset = NULL, recursive = TRUE, simplify = FALSE, include_input = FALSE, value = NULL, ...) subtaxa_apply(obj, func, subset = NULL, recursive = TRUE, simplify = FALSE, include_input = FALSE, value = NULL, ...)
The taxonomy() or taxmap() object containing taxon
information to be queried.
(function) The function to apply.
(character) taxon_ids or indexes of
taxon_data for which supertaxa will be returned. Default: All taxa
in obj will be used.
(logical or numeric) If FALSE, only return the
supertaxa one rank above the target taxa. If TRUE, return all the
supertaxa of every supertaxa, etc. Positive numbers indicate the number of
recursions (i.e. number of ranks above the target taxon to return). 1 is
equivalent to FALSE. Negative numbers are equivalent to TRUE.
(logical) If TRUE, then combine all the results into a
single vector of unique values.
(logical) If TRUE, the input taxa are included in
the output
What data to give to the function. Any result of
all_names(obj) can be used, but it usually only makes sense to use data
that has an associated taxon id.
Extra arguments are passed to the function.
