Measurement of Biodiversity in R

This repository hosts an R package that is actively being developed for
estimating biodiversity and the components of its change. The key innovations of
this R package over other R packages that also carry out rarefaction (e.g.,
vegan, iNext) is that mobr is focused on 1) making empirical comparisons between
treatments or gradients, and 2) our framework emphasizes how changes in
biodiversity are linked to changes in community structure: the SAD, total
abundance, and spatial aggregation.

The concepts and methods behind this R package are described in three publications.

Please cite mobr. Run the following to get the appropriate citation for the version you're using:

citation(package = "mobr")

Installation

install.packages('mobr')

Or, install the Github version

install.packages('remotes')

Now that remotes is installed you can install mobr using the following R code:

remotes::install_github('MoBiodiv/mobr')

Examples

The package vignette
provides a useful walk-through the package tools, but below is some example code
that uses the two key analyses and related graphics.

library(mobr)
library(dplyr)

data(tank_comm)
data(tank_plot_attr)
indices <- c('N', 'S', 'S_n', 'S_C', 'S_PIE')
tank_div <- tibble(tank_comm) %>% 
  group_by(group = tank_plot_attr$group) %>% 
  group_modify(~ calc_comm_div(.x, index = indices, effort = 5,
                               extrapolate = TRUE))
plot(tank_div)
tank_mob_in <- make_mob_in(tank_comm, tank_plot_attr, coord_names = c('x', 'y'))
tank_deltaS <- get_delta_stats(tank_mob_in, 'group', ref_level='low',
                             type='discrete', log_scale=TRUE, n_perm = 5)
plot(tank_deltaS, 'b1')
