Compute regional time series of Individual Species Mean Pairwise trait distance

Usage

IndivSpecies_regional_mpd(
  df.TS.TE,
  time.slice,
  trait = NULL,
  dist.trait = NULL,
  nearest.taxon = "all",
  round.digits = 1,
  species = "species",
  TS = "TS",
  TE = "TE"
)

Arguments

df.TS.TE: a data frame object containing at least four columns. Species names, origination time, extinction time and a trait value for each species.
time.slice: scalar indicating the time interval between consecutive time slices
trait: Character indicating the name of the column containing values of the traits for each species. If NULL, the default, the user must provide a distance matrix
dist.trait: A distance matrix containing pairwise distance between species. If NULL the default, the user must provide a trait in trait argument
nearest.taxon: scalar indicating the number of closest species that will be used to compute the mean pairwise distance. If "all", the default, all species coexisting in a time slice will be used to calculate mpd
round.digits: scalar indicating the number of digits for time of origination and time for extinction
species: character indicating the name of the column of the data frame containing the species name information
TS: character indicating the name of the columns of the data frame containing the information on origination time
TE: character indicating the name of the column of the data frame containing the information on extinction time

Value

A data frame containing the name of species and the mean value of mpd of each species in each time slice
