This set of scales defines new size scales for edge labels in order to allow
for separate sizing of edges and their labels.
scale_label_size_continuous(..., range = c(1, 6))
scale_label_size(..., range = c(1, 6))
scale_label_size_discrete(..., range = c(2, 6))
scale_label_size_manual(..., values)
scale_label_size_identity(..., guide = "none")
Arguments
... 
Arguments passed on to continuous_scale
 name
The name of the scale. Used as the axis or legend title. If
waiver() , the default, the name of the scale is taken from the first
mapping used for that aesthetic. If NULL , the legend title will be
omitted.
 breaks
One of:
NULL for no breaks
waiver() for the default breaks computed by the
transformation object
A numeric vector of positions
A function that takes the limits as input and returns breaks
as output
 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.
 labels
One of:
NULL for no labels
waiver() for the default labels computed by the
transformation object
A character vector giving labels (must be same length as breaks )
A function that takes the breaks as input and returns labels
as output
 limits
One of:
NULL to use the default scale range
A numeric vector of length two providing limits of the scale.
Use NA to refer to the existing minimum or maximum
A function that accepts the existing (automatic) limits and returns
new limits
 oob
Function that handles limits outside of the scale limits
(out of bounds). The default replaces out of bounds values with NA .
 na.value
Missing values will be replaced with this value.
 trans
Either the name of a transformation object, or the
object itself. Builtin transformations include "asn", "atanh",
"boxcox", "date", "exp", "hms", "identity", "log", "log10", "log1p", "log2",
"logit", "modulus", "probability", "probit", "pseudo_log", "reciprocal",
"reverse", "sqrt" and "time".A transformation object bundles together a transform, its inverse,
and methods for generating breaks and labels. Transformation objects
are defined in the scales package, and are called name_trans , e.g.
scales::boxcox_trans() . You can create your own
transformation with scales::trans_new() .
 guide
A function used to create a guide or its name. See
guides() for more info.
 position
The position of the axis. "left" or "right" for vertical
scales, "top" or "bottom" for horizontal scales
 super
The super class to use for the constructed scale
 expand
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 expand_scale()
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.

range 
a numeric vector of length 2 that specifies the minimum and
maximum size of the plotting symbol after transformation. 
values 
a set of aesthetic values to map data values to. If this
is a named vector, then the values will be matched based on the names.
If unnamed, values will be matched in order (usually alphabetical) with
the limits of the scale. Any 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 info. 
Value
A ggproto object inheriting from Scale
