R: Edge label size scales

scale_label_size {ggraph} | R Documentation

## Edge label size scales

### Description

This set of scales defines new size scales for edge labels in order to allow for separate sizing of edges and their labels.

### Usage

    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. 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()`. 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`
