Usage

aggregate_taxa(x, FUN = sum)

Arguments

x	Result of as_biomonitor().
FUN	The function to be applied for aggregating at higher taxonomic levels. Must be sum for both abundances and presence-absence data. Default to sum().

Examples

data(macro_ex)
data_bio <- as_biomonitor(macro_ex)
data_agr <- aggregate_taxa(data_bio)

# example for macrophytes
data(oglio)

oglio_asb <- as_biomonitor(oglio, group = "mf")
oglio_agg <- aggregate_taxa(oglio_asb)
richness(oglio_agg, tax_lev = "Species")
richness(oglio_agg, tax_lev = "Genus")
richness(oglio_agg, tax_lev = "Family")
