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.

scale_edge_size_continuous(..., 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")

Arguments

... Arguments passed on to continuous_scale nameThe 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. breaksOne 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_breaksOne 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. labelsOne 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 limitsOne 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 oobFunction that handles limits outside of the scale limits (out of bounds). The default replaces out of bounds values with NA. na.valueMissing values will be replaced with this value. transEither the name of a transformation object, or the object itself. Built-in 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(). guideA function used to create a guide or its name. See guides() for more info. positionThe position of the axis. "left" or "right" for vertical scales, "top" or "bottom" for horizontal scales superThe super class to use for the constructed scale expandVector 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. 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. 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. A function used to create a guide or its name. See guides() for more info.

Value

A ggproto object inheriting from Scale

Note

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

Other scale_edge_*: scale_edge_alpha(), scale_edge_colour, scale_edge_fill, scale_edge_linetype(), scale_edge_shape(), scale_edge_width(), scale_label_size()
