align ObjectAn Align object interacts with the Layout object to reorder or
split observations and, in some cases, add plot components to the Layout.

)A new ggalign_plot object.
An Align object.
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.
A ggplot object.
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.
Options for schemes:
NULL: Used when align do not add a plot.
waiver(): Try to infer schemes based on data.
Logical; if
TRUE,
removes axes elements for the alignment axis using theme_no_axes(). By
default, will use the option-
"ggalign.align_no_axes".
A active() object that defines the context settings when
added to a layout.
The call used to construct the Align object, for reporting
messages.
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).
Each of the Align* objects is just a ggproto()
object, descended from the top-level Align, 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.
