View source: R/measures_for_abundance_matrices.R

Calculates covariance or correlation matrix from a community abundance or incidence matrix where species are rows and sites are columns. Note: Before the calculation, species (rows) with zero occurrences, and sites (columns) with zero species are removed from m.

1	CA_cov_cor(m, transf = NULL, correlation = TRUE, method = "pearson")

`m`	Community data matrix with species as rows and sites as columns. Can contain either incidences (1/0) or abundances (natural numbers).
`transf`	A transformation function to be applied to the community matrix. The default is no transformation. Other options from 'vegan' function 'decostand' are applicable.
`correlation`	Should correlations be returned (TRUE) or covariances (FALSE).
`method`	One of 'peason' (default), 'kendall', or 'spearman'. is the default.
