Plot categorical variable probabilities

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

x: An object for which a method exists
variables: A character vectors with the names of the variables to be plotted (optional).
bars: Atomic character, indicating what separate bars represent. One of c("Variable", "group", "class").
facet: Atomic character, indicating what separate facets represent. One of c("group", "class", "Variable").
bw: Logical. Should the plot be black and white (for print), or color?
...: Arguments passed to and from other functions.

Value

An object of class 'ggplot'.
