scale_edge_fill: Edge fill scales

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

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_viridis(..., alpha = 1, begin = 0, end = 1,
  discrete = FALSE, option = "D", direction = 1)

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
alpha	pass through parameter to viridis
begin	The (corrected) hue in [0,1] at which the viridis colormap begins.
discrete	generate a discrete palette? (default: FALSE - generate continuous palette)
option	A character string indicating the colormap option to use. Four options are available: "magma" (or "A"), "inferno" (or "B"), "plasma" (or "C"), and "viridis" (or "D", the default option).

Value
