This function plots the posterior predictive samples generated by
posterior.predictive.sample around the observed data, so that users can
evaluate how well the model is able to describe their data.
The output file generated by the function posterior.predictive.sample.
save.figure
If save.figure = TRUE, a .png file of the posterior predictive sample plot
will be saved, rather than plotted to the default R plotting window. Depending on the
posterior.predictive.sample.size specified in
posterior.predictive.sample, this figure may be time-intensive to generate,
so users may wish to save the figure for future analysis, rather than re-plot it. If
save.figure = TRUE, a figure.name must be specified.
Default is save.figure = NULL.
figure.name
If save.figure = TRUE, a .png file of the posterior predictive sample plot
will be saved under the name figure.name. If save.figure = TRUE, a
figure.name must be specified. Default is figure.name = NULL.
Details
This function plots posterior predictive unbiased pairwise F_{ST} around the
observed unbiased pairwise F_{ST} values to determine how well the model is
able to describe the user's data. Users should examine these plots to make sure that
the model is picking up general trends (e.g. the slopes of isolation by geographic
distance and isolation by ecological distance), and also to identify specific
populations whose relationships with their neighbors are being poorly accommodated by
the model.
