Print a summary of model results to the R console, or plot posterior distributions of model parameters.
## S3 method for class 'geostan_fit'print(x, probs = c(0.025,0.2,0.5,0.8,0.975), digits =3, pars =NULL,...)## S3 method for class 'geostan_fit'plot(x, pars, plotfun ="hist", fill ="steelblue4",...)
Arguments
x: A fitted model object of class geostan_fit.
probs: Argument passed to quantile; which quantiles to calculate and print.
digits: number of digits to print
pars: parameters to include; a character string (or vector) of parameter names.
...: additional arguments to rstan::plot or rstan::print.stanfit.
plotfun: Argument passed to rstan::plot. Options include histograms ("hist"), MCMC traceplots ("trace"), and density plots ("dens"). Diagnostic plots are also available such as Rhat statistics ("rhat"), effective sample size ("ess"), and MCMC autocorrelation ("ac").
fill: fill color for histograms and density plots.
Returns
The print methods writes text to the console to summarize model results. The plot method resturns a ggplot (from rstan::plot for stanfit objects).
