make.env: Generates environmental variables

In richardjtelford/palaeoSig: Significance Tests for Palaeoenvironmental Reconstructions

Generates environmental variables

Description

Generates environmental variables used for generating species abundances. Environmental variables may be correlated, and may follow different distributions.

Usage

make.env(n, elen, emean, edistr, ecor, ndim)

Arguments

n	Number of samples to be generated.
elen	Range of the environmental variables. Single number or vector of length ndim.
emean	Mean of the environmental variables. Single number or vector of length ndim.
edistr	Distribution of the environmental variables. Currently 'uniform' and 'Gaussian' are supported.
ecor	Correlation matrix of the environmental variables supplied by user. Object generated by cor.mat.fun. If omitted environmental variables are not correlated.
ndim	Number of environmental variables to generate.

Value

Matrix of environmental variables. n rows and ndim columns.
