Taxonomic Richness

taxa_rich(
  .dataframe,
  .key_col,
  .group_col,
  .counts_col,
  .filter = NULL,
  .unnest_col = NULL
)

`.dataframe`	A data frame where each row should represent the number of individuals enumerated for a single taxon collected during a single sampling event.
`.key_col`	One unquoted column name that represents a key (i.e., unique ID) for a sampling event for which to group (i.e., aggregate) the data.
`.group_col`	One unquoted column name that represents a taxomic rank or group of interest.
`.counts_col`	One unquoted column name that represents taxonomic counts. zero counts are filtered out of the richness count.
`.filter`	A logical statement to subset the data frame prior to calculating the metric of interest.
`.unnest_col`	One unqouted column name that represents nested data. If this column is NULL (default), then the data will not be unnested.
