scale_edge_width: Edge width scales

In YTLogos/ggraph: An Implementation of Grammar of Graphics for Graphs and Networks

Description

This set of scales defines width scales for edge geoms. Of all the new edge scales defined in ggraph, this is the only one not having an equivalent in ggplot2. In essence it mimicks the use of size in geom_line and related. As almost all edge representations are lines of some sort, edge_width will be used much more often than edge_size. It is not necessary to spell out that it is an edge scale as the geom knows if it is drawing an edge. Just write width and not edge_width in the call to geoms.

Usage

scale_edge_width_continuous(..., range = c(1, 6))

scale_edge_width(..., range = c(1, 6))

scale_edge_width_discrete(..., range = c(2, 6))

scale_edge_width_manual(..., values)

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

Arguments

...	Other arguments passed on to continuous_scale to control name, limits, breaks, labels and so forth.
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	Name of guide object, or object itself.

Value

A ggproto object inheriting from Scale
