stat_debug_panel: Print to console data received by the compute panel function.

Description

stat_debug reports all distinct values in group and PANEL, and nrow, ncol and the names of the columns or variables, and the class of x and y for each panel in a ggplot as passed to the compute_panel function in the ggproto object.

Usage

stat_debug_panel(mapping = NULL, data = NULL, geom = "null",
  summary.fun = tibble::as_tibble, summary.fun.args = list(),
  position = "identity", na.rm = FALSE, show.legend = FALSE,
  inherit.aes = TRUE, ...)

Arguments

mapping

The aesthetic mapping, usually constructed with aes or aes_. Only needs to be set at the layer level if you are overriding the plot defaults.

data

A layer specific dataset - only needed if you want to override the plot defaults.

geom

The geometric object to use display the data

summary.fun

A function used to print the data object received as input.

summary.fun.args

A list.

position

The position adjustment to use for overlapping points on this layer

na.rm

a logical value indicating whether NA values should be stripped before the computation proceeds.

show.legend

logical. Should this layer be included in the legends? NA, the default, includes if any aesthetics are mapped. FALSE never includes, and TRUE always includes.

inherit.aes

If FALSE, overrides the default aesthetics, rather than combining with them. This is most useful for helper functions that define both data and aesthetics and shouldn't inherit behaviour from the default plot specification, e.g. borders.

...

other arguments passed on to layer. This can include aesthetics whose values you want to set, not map. See layer for more details.

Computed variables

x

x at centre of range

y

y at centre of range

nrow

nrow() of data object

ncol

ncol() of data object

colnames

colnames() of data object

colclasses

class() of x and y columns in data object

group

all distinct values in group as passed in data object

PANEL

all distinct values in PANEL as passed in data object
