Coord: Coordinate systems

In paleolimbot/ggr6: An Implementaation of the Grammar of Graphics in R6

Description

Coordinate systems pick which aesthetics are position aesthetics, finalize the Panel at the end of the build process, and transform coordinates. Regardless of their aesthetics, they should always return from their $transform() method a data frame with x and y columns. The default CoordIdentity does not change the Panel and performs no changes in its $transform() method.

Methods

Public methods

• Coord$new()

• Coord$transform()

• Coord$finalize_panel()

• Coord$clone()

---

Method new()

Usage

Coord$new(aesthetics = c("x", "y"))

Details

Create a coordinate system representing one or more position aesthetics.

---

Method transform()

Usage

Coord$transform(data_mapped, scales)

Details

Transform a data frame containing columns representing one or more position $aesthetics. This method should always return a data frame with x and y columns and leave non-position columns unchanged.

---

Method finalize_panel()

Usage

Coord$finalize_panel(panel)

Details

Finalize the Panel object at the end of the build process. This is where scale expansion (if any) can occur.

---

Method clone()

The objects of this class are cloneable with this method.

Usage

Coord$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.

Super class

ggr6::Coord -> CoordIdentity

---

Method finalize_panel()

Usage

CoordIdentity$finalize_panel(panel)

---

Method clone()

The objects of this class are cloneable with this method.

Usage

CoordIdentity$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.
