Summarise biological nitrogen fixation results.

Source: R/bnf.R
summarize_bnf.Rd

Aggregates the per-row BNF components into group totals, shares and mean modifiers.

Usage

summarize_bnf(x, group_by = "item_prod_code")

Arguments

x

A tibble with crop_bnf_t, weed_bnf_t, nonsymbiotic_bnf_t and bnf_t (the output of calculate_bnf()).

group_by

Character vector of grouping columns (default "item_prod_code"); use NULL for an overall summary.

Value

A tibble with per-group counts, BNF totals, component percentages and mean environmental factors.

Examples

tibble::tibble(
  item_prod_code = "176", crop_npp_n_t = 10, product_n_t = 5,
  weed_npp_n_t = 4, land_use = "Cropland", legumes_seeded = 0,
  seeded_cover_crop_share = 0, area_ha = 40
