stack_layout: Arrange plots horizontally or vertically

In ggalign: A 'ggplot2' Extension for Consistent Axis Alignment

Arrange plots horizontally or vertically

Description

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

Several aliases are provided for convenience:

• stack_vertical: A special case of stack_layout that sets direction = "v".

• stack_horizontal: A special case of stack_layout that sets direction = "h".

• stack_discretev: A special case of stack_discrete that sets direction = "v".

• stack_discreteh: A special case of stack_discrete that sets direction = "h".

• stack_continuousv(): A special case of stack_free that sets direction = "v".

• stack_continuoush(): A special case of stack_free that sets direction = "h".

For historical reasons, the following aliases are available:

• stack_align is an alias for stack_discrete.

• stack_alignv is an alias for stack_discretev.

• stack_alignh is an alias for stack_discreteh.

• stack_free is an alias for stack_continuous.

• stack_freev is an alias for stack_continuousv.

• stack_freeh is an alias for stack_continuoush.

Usage

stack_layout(
  direction,
  data = NULL,
  ...,
  theme = NULL,
  sizes = NA,
  limits = waiver()
)

stack_horizontal(data = NULL, ..., limits = waiver())

stack_vertical(data = NULL, ..., limits = waiver())

stack_discrete(direction, data = NULL, ..., theme = NULL, sizes = NA)

stack_discretev(data = NULL, ...)

stack_discreteh(data = NULL, ...)

stack_continuous(
  direction,
  data = NULL,
  ...,
  limits = NULL,
  theme = NULL,
  sizes = NA
)

stack_continuousv(data = NULL, ...)

stack_continuoush(data = NULL, ...)

Arguments

direction	A string indicating the direction of the stack layout, either "h"(horizontal) or "v"(vertical).
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().
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.
sizes	A numeric value or a unit object. When used for the quad_layout() annotation, it must be of length 1. When used in the stack_layout() with a nested quad_layout(), it should be of length 3, specifying the relative heights (for direction = "h") or widths (for direction = "v") to be applied to the layout.
limits	A continuous_limits() object specifying the left/lower limit and the right/upper limit of the scale. Used to align the continuous axis.

Value

A StackLayout object.

Examples

set.seed(123)
small_mat <- matrix(rnorm(56), nrow = 7L)

stack_horizontal(small_mat) + align_dendro()

# this is the same with:
stack_discrete("h", small_mat) + align_dendro()

stack_discreteh(small_mat) + align_dendro()

# For vertical layout:
stack_vertical(small_mat) + align_dendro()
