scale_edge_colour: Edge colour scales

Description

This set of scales defines new colour scales for edge geoms equivalent to the ones already defined by ggplot2. The parameters are equivalent to the ones from ggplot2 so there is nothing new under the sun. The different geoms will know whether to use edge scales or the standard scales so it is not necessary to write edge_colour in the call to the geom - just use colour.

Usage

scale_edge_colour_hue(..., h = c(0, 360) + 15, c = 100, l = 65, h.start = 0, direction = 1, na.value = "grey50")

Arguments

...
Other arguments passed on to discrete_scale to control name, limits, breaks, labels and so forth.
h
range of hues to use, in [0, 360]
c
chroma (intensity of colour), maximum value varies depending on combination of hue and luminance.
l
luminance (lightness), in [0, 100]
h.start
hue to start at
direction
direction to travel around the colour wheel, 1 = clockwise, -1 = counter-clockwise
na.value
Colour to use for missing values
type
One of seq (sequential), div (diverging) or qual (qualitative)
palette
If a string, will use that named palette. If a number, will index into the list of palettes of appropriate type
values
if colours should not be evenly positioned along the gradient this vector gives the position (between 0 and 1) for each colour in the colours vector. See rescale for a convience function to map an arbitrary range to between 0 and 1.
space
colour space in which to calculate gradient. Must be "Lab" - other values are deprecated.
guide
Type of legend. Use "colourbar" for continuous colour bar, or "legend" for discrete colour legend.
low, high
Colours for low and high ends of the gradient.
mid
colour for mid point
midpoint
The midpoint (in data value) of the diverging scale. Defaults to 0.
colours, colors
Vector of colours to use for n-colour gradient.
start
gray value at low end of palette
end
gray value at high end of palette

Value

A ggproto object inheriting from Scale
