circle_layout: Arrange plots in a circular layout

Description

If limits is provided, a continuous variable will be required and aligned in the direction specified (circle_continuous). Otherwise, a discrete variable will be required and aligned (circle_discrete).

Usage

circle_layout(
  data = NULL,
  ...,
  radial = NULL,
  direction = "outward",
  limits = waiver(),
  theme = NULL
)
circle_discrete(
  data = NULL,
  ...,
  radial = NULL,
  direction = "outward",
  spacing_theta = NULL,
  theme = NULL
)
circle_continuous(
  data = NULL,
  ...,
  radial = NULL,
  direction = "outward",
  limits = NULL,
  theme = NULL
)

Value

A CircleLayout object.

Arguments

data

Default dataset to use for the layout. If not specified, it must be supplied in each plot added to the layout:

• If limits is not provided, fortify_matrix() will be used to get a matrix.

• If limits is specified, fortify_data_frame() will be used to get a data frame.

...

Additional arguments passed to fortify_data_frame() or fortify_matrix().

radial

A coord_circle()/coord_radial() object that defines the global parameters for coordinate across all plots in the layout. The parameters start, end, direction, and expand will be inherited and applied uniformly to all plots within the layout. The parameters theta and r.axis.inside will always be ignored and will be set to "x" and TRUE, respectively, for all plots.

direction

A single string of "inward" or "outward", indicating the direction in which the plot is added.

• outward: The plot is added from the inner to the outer.

• inward: The plot is added from the outer to the inner.

limits

A continuous_limits() object specifying the left/lower limit and the right/upper limit of the scale. Used to align the continuous axis.

theme

A theme() object used to customize various elements of the layout, including guides, title, subtitle, caption, margins, panel.border, and background. By default, the theme will inherit from the parent layout. It also controls the panel spacing for all plots in the layout.

spacing_theta

The size of spacing between different panel. A numeric of the radians or a rel() object.
