Triangle-heatmap view of dev-sequence gaps — plot_triangle.TriangleValidation • lossratio

Visualise gap positions on a cohort x dev grid: for every cohort with gaps, expanded dev cells are coloured by status (observed / missing). Complements plot.TriangleValidation() (which shows observed-vs-expected counts as bars) – this heatmap shows where the gaps are.

When the validation found no gaps, prints a message and returns invisible(NULL).

Usage

# S3 method for class 'TriangleValidation'
plot_triangle(
  x,
  view = c("calendar", "dev"),
  show_label = FALSE,
  theme = c("view", "save", "shiny"),
  ...
)

Arguments

x: A TriangleValidation object.
view: Axis layout. One of "calendar" (cohort x calendar grid, default) or "dev" (cohort x dev grid). "calendar" requires the calendar column to have been supplied to validate_triangle(); "dev" works when either calendar or dev was supplied.
show_label: Logical; when TRUE, overlay each cell with the input row count (.N). Default FALSE.
theme: String passed to .switch_theme().
...: Extra arguments passed to .switch_theme().

Value

A ggplot object, or invisible(NULL) when there is nothing to visualise.
