Comparing simulations against theoretical expectations

Description

Comparing simulations against theoretical expectations

Usage

gl.diagnostics.sim(
  x,
  Ne,
  iteration = 1,
  pop_he = 1,
  pops_fst = c(1, 2),
  plot_theme = theme_dartR(),
  save2tmp = FALSE,
  verbose = NULL
)

Arguments

x	Output from function gl.sim.WF.run [required].
Ne	Effective population size to use as input to compare theoretical expectations [required].
iteration	Iteration number to analyse [default 1].
pop_he	Population name in which the rate of loss of heterozygosity is going to be compared against theoretical expectations [default 1].
pops_fst	Pair of populations in which FST is going to be compared against theoretical expectations [default c(1,2)].
plot_theme	User specified theme [default theme_dartR()].
save2tmp	If TRUE, saves any ggplots and listings to the session temporary directory (tempdir) [default FALSE].
verbose	Verbosity: 0, silent or fatal errors; 1, begin and end; 2, progress log ; 3, progress and results summary; 5, full report [default NULL, unless specified using gl.set.verbosity].

Details

Two plots are presented comparing the simulations against theoretical expectations:

1. Expected heterozygosity under neutrality (Crow & Kimura, 1970, p. 329) is calculated as:

   Het = He0(1-(1/2Ne))^t,

   where Ne is effective population size, He0 is heterozygosity at generation 0 and t is the number of generations.

2. Expected FST under neutrality (Takahata, 1983) is calculated as:

   FST=1/(4Nem(n/(n-1))^2+1),

   where Ne is effective populations size of each individual subpopulation, m is dispersal rate and n the number of subpopulations (always 2).

Value

Returns plots comparing simulations against theoretical expectations
