betavolume: Load a Matrix corresponds to metacommunity composition

In clsong/BetaVolume: A geometric measure of beta diversity in metacommunities

Load a Matrix corresponds to metacommunity composition

Description

This function loads a file as a matrix. It assumes that columns correspond to local communities (plots or patches) while the columns correspond to species. The matrix entries correspond to species property (e.g, presence/absence).

Usage

betavolume(
  meta_composition,
  preprocess = T,
  weights = F,
  remove_unique = F,
  hypervolume_method,
  compressed_angle = 1,
  dim_threshold = 10,
  sparsity = F
)

Arguments

meta_composition	metacommunity composition
preprocess	Whether weights and remove_unique should be executed
weights	whether non-unique compositions should be weighted
remove_unique	whether unique compositions should be removed
hypervolume_method	which method to estimate the hypervolume
compressed_angle	how much the original hypervolume is changed by the similarity matrix
dim_threshold	the threshold of which default hypervolume_method is used
sparsity	whether the meta_composition is encoded as a sparse matrix

Value

the value of the geometric measure of beta_diversity
