scale_edge_shape

Edge shape scales

Description

This set of scales defines new shape scales for edge geoms equivalent to the ones already defined by ggplot2. See ggplot2::scale_shape() 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_shape in the call to the geom - just use shape.

Usage

scale_edge_shape(..., solid = TRUE)

scale_edge_shape_discrete(..., solid = TRUE)

scale_edge_shape_continuous(...)

scale_edge_shape_manual(..., values)

scale_edge_shape_identity(..., guide = "none")

Arguments

`...`	Arguments passed on to `discrete_scale` `palette` A palette function that when called with a single integer argument (the number of levels in the scale) returns the values that they should take (e.g., `scales::hue_pal()`). `breaks` One of: `NULL` for no breaks `waiver()` for the default breaks (the scale limits) A character vector of breaks A function that takes the limits as input and returns breaks as output `limits` One of: `NULL` to use the default scale values A character vector that defines possible values of the scale and their order A function that accepts the existing (automatic) values and returns new ones `drop` Should unused factor levels be omitted from the scale? The default, `TRUE`, uses the levels that appear in the data; `FALSE` uses all the levels in the factor. `na.translate` Unlike continuous scales, discrete scales can easily show missing values, and do so by default. If you want to remove missing values from a discrete scale, specify `na.translate = FALSE`. `na.value` If `na.translate = TRUE`, what aesthetic value should the missing values be displayed as? Does not apply to position scales where `NA` is always placed at the far right. `aesthetics` The names of the aesthetics that this scale works with. `scale_name` The name of the scale that should be used for error messages associated with this 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. `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 `guide` A function used to create a guide or its name. See `guides()` for more information. `super` The super class to use for the constructed scale
`solid`	Should the shapes be solid, `TRUE`, or hollow, `FALSE`?
`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`	Guide to use for this scale.
