scale_edge_size: Edge size scales

Description

This set of scales defines new size scales for edge geoms equivalent to the ones already defined by ggplot2. See ggplot2::scale_size() for more information. The different geoms will know whether to use edge scales or the standard scales so it is not necessary to write edge_size in the call to the geom - just use size.

Usage

scale_edge_size_continuous(..., range = c(1, 6))
scale_edge_radius(..., range = c(1, 6))
scale_edge_size(..., range = c(1, 6))
scale_edge_size_discrete(..., range = c(2, 6))
scale_edge_size_area(..., max_size = 6)
scale_edge_size_manual(..., values)
scale_edge_size_identity(..., guide = "none")

Value

A ggproto object inheriting from Scale

Arguments

...

Arguments passed on to continuous_scale

minor_breaks

One of:

• NULL for no minor breaks

• waiver() for the default breaks (one minor break between each major break)

• A numeric vector of positions

• A function that given the limits returns a vector of minor breaks. Also accepts rlang lambda function notation.

oob

One of:

• Function that handles limits outside of the scale limits (out of bounds). Also accepts rlang lambda function notation.

• The default (scales::censor()) replaces out of bounds values with NA.

• scales::squish() for squishing out of bounds values into range.

• scales::squish_infinite() for squishing infinite values into range.

na.value

Missing values will be replaced with this value.

expand

For position scales, a vector of range expansion constants used to add some padding around the data to ensure that they are placed some distance away from the axes. Use the convenience function expansion() to generate the values for the expand argument. The defaults are to expand the scale by 5% on each side for continuous variables, and by 0.6 units on each side for discrete variables.

position

For position scales, The position of the axis. left or right for y axes, top or bottom for x axes.

super

The super class to use for the constructed scale

range

a numeric vector of length 2 that specifies the minimum and maximum size of the plotting symbol after transformation.

max_size

Size of largest points.

values

a set of aesthetic values to map data values to. The values will be matched in order (usually alphabetical) with the limits of the scale, or with breaks if provided. If this is a named vector, then the values will be matched based on the names instead. Data values that don't match will be given na.value.

guide

A function used to create a guide or its name. See guides() for more information.
