scale_edge_fill: Edge fill scales

Description

This set of scales defines new fill 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_fill in the call to the geom - just use fill.

Usage

scale_edge_fill_hue(..., h = c(0, 360) + 15, c = 100, l = 65, h.start = 0, direction = 1, na.value = "grey50")
scale_edge_fill_brewer(..., type = "seq", palette = 1, direction = 1)
scale_edge_fill_distiller(..., type = "seq", palette = 1, direction = -1, values = NULL, space = "Lab", na.value = "grey50", guide = "edge_colourbar")
scale_edge_fill_gradient(..., low = "#132B43", high = "#56B1F7", space = "Lab", na.value = "grey50", guide = "edge_colourbar")
scale_edge_fill_gradient2(..., low = muted("red"), mid = "white", high = muted("blue"), midpoint = 0, space = "Lab", na.value = "grey50", guide = "edge_colourbar")
scale_edge_fill_gradientn(..., colours, values = NULL, space = "Lab", na.value = "grey50", guide = "edge_colourbar", colors)
scale_edge_fill_grey(..., start = 0.2, end = 0.8, na.value = "red")
scale_edge_fill_identity(..., guide = "none")
scale_edge_fill_manual(..., values)
scale_edge_fill_continuous(..., low = "#132B43", high = "#56B1F7", space = "Lab", na.value = "grey50", guide = "edge_colourbar")
scale_edge_fill_discrete(..., 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
