make.env

Number of samples to be generated.

Range of the environmental variables. Single number or vector of length ndim.

elen

Mean of the environmental variables. Single number or vector of length ndim.

emean

Distribution of the environmental variables. Currently 'uniform' and 'Gaussian' are supported.

edistr

Correlation matrix of the environmental variables supplied by user. Object generated by <code><a rd-options="" href="/link/cor.mat.fun?package=palaeoSig&version=2.0-3" data-mini-rdoc="palaeoSig::cor.mat.fun">cor.mat.fun</a></code>. If omitted environmental variables are not correlated.

ecor

Number of environmental variables to generate.

ndim

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

 datagen 

Several tests of quantitative palaeoenvironmental reconstructions
from microfossil assemblages, including the null model tests of the
statistically significant of reconstructions developed by Telford and Birks
(2011) <doi:10.1016/j.quascirev.2011.03.002>, and tests of the effect of
spatial autocorrelation on transfer function model performance using methods
from Telford and Birks (2009) <doi:10.1016/j.quascirev.2008.12.020> and
Trachsel and Telford (2016) <doi:10.5194/cp-12-1215-2016>. Age-depth models with
generalized mixed-effect regression from Heegaard et al (2005)
<doi:10.1191/0959683605hl836rr> are also included.
