BEST (version 0.5.3)

plotAll: A series of plots displaying the results of 'BEST' analysis.

Description

Displays a series of plots showing the posterior probability distributions of the parameters of interest.

Usage

plotAll(BESTobj, credMass = 0.95,
  ROPEm = NULL, ROPEsd = NULL, ROPEeff = NULL,
  compValm = 0, compValsd = NULL, compValeff = 0,
  showCurve = FALSE, ...)

Arguments

BESTobj

an object of class BEST, as produced by the function BESTmcmc.

credMass

the probability mass to include in credible intervals, or NULL to suppress plotting of the credible interval.

ROPEm

a two element vector, such as c(-1, 1), specifying the limit of the ROPE on the difference of means (for 2 groups) or the mean (for 1 group).

ROPEsd

a two element vector, such as c(-1, 1), specifying the limit of the ROPE on the (difference of) standard deviations.

ROPEeff

a two element vector, such as c(-1, 1), specifying the limit of the ROPE on the effect size.

showCurve

logical: if TRUE, the posterior density will be represented by a kernel density function instead of a histogram.

compValm

a value for comparison with the (difference of) means.

compValsd

a value for comparison with the (difference of) standard deviations.

compValeff

a value for comparison with the effect size.

...

other graphical parameters (currently ignored).

Value

Returns NULL invisibly. Used for the side effect.

Details

The display has a series of panels displaying the posterior distributions of each of the parameters (and differences between groups) together with summary statistics; see plotPost for details. Also a chart showing approx. 30 plots of posterior predictive distributions, together with histograms of the original data.
