check.packages: Check for required packages

In akeyel/spatialdemography: A Spatially Explicit Metacommunity Model

Description

This function checks that all required packages needed to run SpatialDemography are present and usable. Packages to check are: Matrix, multirich, FD, and copula. spatialdemography may also use lhs and raster, but these are used in exported functions that contain their own checks. Hmisc, quantreg & gbm were formerly listed under suggests, but are currently not part of the code workflow (i.e. they would require an external call to an internal function) lattice was formerly listed under suggests, but I don't think it was actually used so it is no longer listed nor is it checked for.are not integrated into the code.

Usage

check.packages(out.metrics, include.copula)

Arguments

out.metrics	A vector of potential metrics to calculate. Those ending in UTC will require multirich to calculate, and those ending in FRIC will require FD to calculate. At some point, I need to add in Petchey & Gaston's FD metric.
include.copula	An entry from the settings file. If null or 0, the copula package is not required.
