Calculate individual species coexistence in regional scale

Usage

IndivSpecies_regional_coex(
  df.TS.TE,
  time.slice,
  round.digits = 1,
  species = "species",
  TS = "TS",
  TE = "TE"
)

df.TS.TE: a data frame object containing at least three columns. Species names, origination time and extinction time for each species.
time.slice: scalar indicating the time interval between consecutive time slices
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

A list with two elements:

df_IndivSpp_coexist: A data frame with species name, the number of coexistence for each sepecies in each time slice
mean_species_coexistence: A data frame with three column. The species name, the mean number of coexistence for each species and the variance considering all time slices
