zeroTest(logfile, pars, cols = 2, plot = TRUE, value = 0, thinning = 1,
  burnin = 0)

Arguments

logfile

The name of the BayesTraits output logfile.

pars

A vector of parameters to plot/summarise

cols

The number of columns to plot into (if number of pars >1)

plot

If true, a histogram coloured according to value is plotted. If false, a table summarising the posterior with respect to value is printed to screen.

value

The value against which to test (defaults to zero)

thinning

Thinning parameter for the posterior - defaults to 1 (all samples). 2 uses every second sample, 3 every third and so on.

burnin

The number of generations to remove from the start of the chain as burnin.
