R2.test: Ramos-Onsins--Rozas Test of Neutrality

Description

This function computes Ramos-Onsins and Rozas's test of neutrality for a set of DNA sequences.

Usage

R2.test(x, B = 1000, theta = 1, plot = TRUE, quiet = FALSE, ...)

Value

a list with two elements: R2 the value of the test statistic

\(R_2\), and P.val the associated P-value. If

B = 0 a single value, the test statistic, is returned

Arguments

x

a DNA matrix (object of class "DNAbin").

B

the number of replicates used for the simulation procedure.

theta

the value of the \(\theta\) population parameter used in the simulation.

plot

a logical value specifying whether to plot the results (TRUE by default).

quiet

a logical value specifying whether to not display the progress of the simulations. The default is FALSE meaning that a progress bar is displayed by default.

...

further arguments passed to hist.
