Creates a bar chart of categorical variable probabilities with bars reflecting the probability of category membership for each category of the observed variable.

plot_prob(
  x,
  variables = NULL,
  bars = c("Variable", "group", "class"),
  facet = c("group", "class", "Variable"),
  bw = FALSE,
  ...
)

Arguments
