  stand = NULL,
  species = NULL,
  abundance = NULL,
  group = NULL,
  row_data = FALSE
)

Arguments

df	A data.frame, which has three cols: stand, species, abundance. Community matrix should be converted using table2df().
stand, species, abundance	A text to specify each column. If NULL, 1st, 2nd, 3rd column will be used.
group	A text to specify group column.
row_data	A logical. TRUE: return row result data of labdsv::indval().

Value

Examples

library(dplyr)
library(tibble)
data(dune, package = "vegan")
data(dune.env, package = "vegan")
df <- 
  dune %>%
  table2df(st = "stand", sp = "species", ab = "cover") %>%
  dplyr::left_join(tibble::rownames_to_column(dune.env, "stand"))
ind_val(df, abundance = "cover", group = "Moisture")
