View trace-plots of output from Bayesian segmentation model

Visualize trace-plots of the number of breakpoints estimated by the model as well as the log marginal likelihood (LML) for each animal ID.

traceplot(data, type)

Arguments

data	A list of model results that is returned as output from segment_behavior.
type	character. The type of data that are being plotted from the Bayesian segmentation model results. Takes either 'nbrks' for the number of breakpoints or 'LML' for the log marginal likelihood.

Value

Trace-plots for the number of breakpoints or the log marginal likelihood are displayed for each of the animal IDs that were analyzed by the segmentation model.

#only retain id and discretized step length (SL) and turning angle (TA) columns

                  select = c(id, SL, TA))
