Plot a nomo_screen audit — plot.nomo

Visual diagnostics complement the numerical screening output. The default evidence map integrates multiple diagnostic signals without converting them into a pass/fail scale. Additional plot types display item-rest relationships, inter-item correlations, response-category use, or missingness.

Usage

# S3 method for class 'nomo_screen'
plot(
  x,
  y = NULL,
  type = c("evidence", "item_rest", "interitem", "responses", "missingness"),
  items = NULL,
  show_values = TRUE,
  ...
)

Arguments

x: A nomo_screen object.
y: Ignored; included for compatibility with the base plot() generic.
type: Plot type: "evidence", "item_rest", "interitem", "responses", or "missingness". "responses" draws a bar for each response category of a categorical item, and a histogram of observed values for a continuous item (item_type "numeric_continuous"). When the selected items mix the two, the categorical items are drawn and the caption names the continuous ones, which can be plotted by passing them as items.
items: Optional character vector of candidate items to display.
show_values: Logical; add numerical labels where useful.
...: Additional arguments, currently ignored.

Value

A ggplot2 plot object.
