This set of scales defines new size scales for edge geoms equivalent to the
ones already defined by ggplot2. See
more information. The different geoms will know whether to use edge scales or
the standard scales so it is not necessary to write
the call to the geom - just use
Arguments passed on to
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
scales::squish() for squishing out of bounds values into range.
scales::squish_infinite() for squishing infinite values into range.
Missing values will be replaced with this value.
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
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.
For position scales, The position of the axis.
right for y axes,
bottom for x axes.
The super class to use for the constructed scale
a numeric vector of length 2 that specifies the minimum and maximum size of the plotting symbol after transformation.
Size of largest points.
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
A function used to create a guide or its name. See
guides() for more information.

In ggplot2 size conflates both line width and point size into one
scale. In ggraph there is also a width scale (
that is used for linewidth. As edges are often represented by lines the width
scale is the most common.
