This function wraps a number of wrapper functions into one big metric + null tester function. Only a single test is performed, with results saved into memory.

metrics)The desired number of species in the input phylogeny
A numeric, specifying the length of a single side of the arena
Mean log of abundance vector from which species abundances will be drawn
Length of vector from which species' locations are drawn. Large values of this parameter dramatically decrease the speed of the function but result in nicer looking communities
Standard deviation of vector from which species' locations are drawn
The geographic distance within which neighboring individuals should be considered to influence the individual in question
The percent of individuals in the total arena that should be considered (as a proportion, e.g. 0.5 = half)
Number of generations over which to run competition simulations
Number of plots to place
Length of one side of desired plot
The number of randomized CDMs, per null, to generate. These are used to compare the significance of the observed metric scores.
The number of cores to be used for parallel processing.
Optional. If not provided, defines the simulations as all of those in defineSimulations. If only a subset of those simulations is desired, then simulations should take the form of a character vector corresponding to named functions from defineSimulations. The available simulations can be determined by running names(defineSimulations()). Otherwise, if the user would like to define a new simulation on the fly, the argument simulations can take the form of a named list of new functions (simulations).
Optional. If not provided, defines the nulls as all of those in defineNulls. If only a subset of those is desired, then nulls should take the form of a character vector corresponding to named functions from defineNulls. The available nulls can be determined by running names(defineNulls()). Otherwise, if the user would like to define a new null on the fly, the argument nulls can take the form of a named list of new functions (nulls).
Optional. If not provided, defines the metrics as all of those in defineBetaMetrics. If only a subset of those is desired, then metrics should take the form of a character vector corresponding to named functions from defineBetaMetrics. The available metrics can be determined by running names(defineBetaMetrics()). If the user would like to define a new metric on the fly, the argument can take the form of a named list of new functions (metrics).
A list with two elements. The first is a list of data frames, with one for each spatial simulation. These provide the observed beta metric scores for each spatial simulation. The second level is a list of lists, one for each spatial simulation. Each of these is a list of data frames. There is one data frame per null model, and it summarizes the randomized metric scores for that null model for that spatial simulation. Note that this is slightly different than the regular linker() function, which does not output these raw metric scores (that function calculates SES and CI as outputs).
This function wraps a number of other wrapper functions into one big beta metric + null performance tester function. Only a single test is run, with results saved into memory. To perform multiple complete tests, use the multiLinker function, which saves results to file.
