Details

Taxon concepts indicated in argument concepts will be merged into a single concept. The new concept inherits the ID and respective attributes from slots taxonRelations and taxonTraits from the first taxon concept indicated in argument concepts.

For convenience the resulting concept can be displayed by setting print_output=TRUE but only when using argument concepts.

An alternative application of this function is implemented through the argument level, where all lower rank taxa will be merged to the indicated level or higher (if parent of merged taxa are at a higher rank).

Examples

## Merge Cyperus papyrus and Cyperus dives
summary(Easplist, c(206, 197))

sp_list <- merge_taxa(object = Easplist, concepts = c(206, 197),
    print_output = TRUE)
