Generic binned trend plotting function — xplot

Following the xpose design pattern, this is a generic template (analogous to xplot_boxplot() or xplot_pairs()) for rendering already-summarized/binned data as connected points and/or lines across a (typically discrete, possibly ordered) x variable. It is not tied to any particular binning or summarization logic – callers are expected to shape their data (eg via opt's post_processing) and build a named implementation on top of it (eg catdv_vs_occ()) rather than calling it directly for everyday use.

Usage

xplot_binned(
  xpdb,
  mapping = NULL,
  group = "variable",
  type = "pl",
  xscale = "discrete",
  yscale = "continuous",
  title = NULL,
  subtitle = NULL,
  caption = NULL,
  tag = NULL,
  plot_name = "binned",
  gg_theme,
  xp_theme,
  opt,
  quiet,
  ...
)

Arguments

xpdb: <xp_xtras> or <xpose_data> object
mapping: ggplot2 style mapping. Expected to include at least x and y.
group: Column name distinguishing multiple summarized series (eg a variable column). Points/lines/smooths are both connected and coloured by this column (see xpose::xplot_scatter() for the same connecting-line convention).
type: String setting the type of plot to be used: point p, line l, and smooth s, or any combination thereof.
xscale: Defaults to discrete.
yscale: Defaults to continuous.
title: Plot title
subtitle: Plot subtitle
caption: Plot caption
tag: Plot tag
plot_name: Metadata name of plot
gg_theme: As in xpose
xp_theme: As in xpose
opt: Processing options for fetched data
quiet: Silence extra debugging output
...: Additional aesthetics, passed to the point, line and smooth layers.

Value

The desired plot

Details

Unlike xpose::xplot_scatter()'s raw per-subject spaghetti plots, xplot_binned() assumes the supplied data is already one row per x/group combination (eg per occasion, per series) – it does no binning, aggregation, or tidying of its own.
