align: Create a New CraftBox Object with CraftAlign craftsman

Description

[Stable]

An CraftAlign object interacts with the Layout object to reorder or split observations and, in some cases, add plot components to the Layout.

Usage

align(
  align,
  data = NULL,
  ...,
  plot = NULL,
  size = NULL,
  schemes = NULL,
  active = NULL,
  no_axes = deprecated(),
  call = caller_call()
)

Value

A new CraftBox object.

Arguments

align

An CraftAlign object.

data

The following options can be used:

  • NULL: No data is set.

  • waiver(): Inherits the data from the layout matrix.

  • A function (including purrr-like lambda syntax): Applied to the layout matrix to transform the data before use. To transform the final plot data, please use scheme_data().

  • A matrix, data.frame, or atomic vector.

...

Additional fields passed to the align object.

plot

A ggplot object.

size

The relative size of the plot, can be specified as a unit(). Note that for circle_layout(), all size values will be interpreted as relative sizes, as this layout type adjusts based on the available space in the circular arrangement.

schemes

Options for schemes:

  • NULL: Used when align do not add a plot.

  • waiver(): Try to infer schemes based on data.

active

A active() object that defines the context settings when added to a layout.

no_axes

[Deprecated] Please add theme() directly to the ggplot instead.

call

The call used to construct the align object, for reporting messages.

Discrete Axis Alignment

It is important to note that we consider rows as observations, meaning vec_size(data)/NROW(data) must match the number of observations along the axis used for alignment (x-axis for a vertical stack layout, y-axis for a horizontal stack layout).

Details

Each of the Align* objects is just a ggproto() object, descended from the top-level CraftAlign, and each implements various methods and fields.

To create a new type of Align* object, you typically will want to override one or more of the following:

  • setup_params: Prepare parameter or check parameters used by this plot.

  • setup_data: Prepare data used by this plot.

  • compute: A method used to compute statistics.

  • align: A method used to group observations into panel or reorder observations.

  • draw: A method used to draw the plot. Must return a ggplot object.
