`nreps`	Number of repetitions using new data.
`niter`	For each simulated data set, number of permutation or bootstrap iterations.
`mc.cores`	Number of cores to use.
`simtype`	Permutations or bootstrap.
`permtype`	This can be used to specify either the permutation type ('within', 'between', or 'between_within'), or if simtype is 'bootstrap', and boottype is 'cases', it is used to specify how cases are resampled, ('groups', 'within', 'both').
`boottype`
