Plot the Occurrence of Missing-Value Gap Sizes

Source: R/plot.check_na_gapsize.R
plot.anivis_check_na_gapsize.Rd

Renders a check_na_gapsize() result (from the anicheck package) as a horizontal bar chart of how often each gap size occurs — an adaptation of ggplot_na_gapsize() from the imputeTS package (Moritz & Gatscha, GPL-3). For every gap length it draws the number of such gaps (indianred) and, optionally, the total missing frames they account for (steelblue, the gap size times its count). Bars are ranked so the most common (or most costly) gaps sit on top; only the top limit are shown. With more than one group, each gets its own panel.

Usage

# S3 method for class 'anivis_check_na_gapsize'
plot(
  x,
  ...,
  ranked_by = c("occurrence", "total"),
  limit = 10,
  include_total = TRUE,
  mode = c("light", "dark")
)

Arguments

x

A check_na_gapsize object (from the anicheck package).

...

Additional arguments (currently unused).

ranked_by

Order bars by "occurrence" (default, gap frequency) or "total" (resulting missing frames).

limit

Maximum number of gap sizes (bars) to show per group, keeping the top-ranked. Default 10.

include_total

Whether to add the steelblue “resulting NAs” bar alongside the occurrence bar. Default TRUE.

mode

Either "light" (default) or "dark"; passed to theme_animovement().

Value

A ggplot object.

Details

The plot is built from an intermediate frame of class anivis_check_na_gapsize_data produced by as_plot_data() — the staging step that mirrors data_plot() in see.
