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
edge_fill in the call to the geom - just use
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 passed on to
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.,
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. Also accepts rlang lambda function notation.
Should unused factor levels be omitted from the scale?
TRUE, uses the levels that appear in the data;
FALSE uses all the levels in the factor.
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.
The name of the scale that should be used for error messages associated with this scale.
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
For position scales, a vector of range expansion constants used to add some
padding around the data to ensure that they are placed some distance
away from the axes. Use the convenience function
to generate the values for the
expand argument. The defaults are to
expand the scale by 5% on each side for continuous variables, and by
0.6 units on each side for discrete variables.
A function used to create a guide or its name. See
guides() for more information.
For position scales, The position of the axis.
right for y axes,
bottom for x axes.
The super class to use for the constructed scale
range of hues to use, in [0, 360]
chroma (intensity of colour), maximum value varies depending on combination of hue and luminance.
luminance (lightness), in [0, 100]
hue to start at
direction to travel around the colour wheel, 1 = clockwise, -1 = counter-clockwise
Colour to use for missing values
One of seq (sequential), div (diverging) or qual (qualitative)
If a string, will use that named palette. If a number, will index into
the list of palettes of appropriate
type. The list of available palettes can found
in the Palettes section.
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 convenience function
to map an arbitrary range to between 0 and 1.
colour space in which to calculate gradient. Must be "Lab" - other values are deprecated.
Type of legend. Use
"colourbar" for continuous
colour bar, or
"legend" for discrete colour legend.
Colours for low and high ends of the gradient.
colour for mid point
The midpoint (in data value) of the diverging scale. Defaults to 0.
Vector of colours to use for n-colour gradient.
grey value at low end of palette
grey value at high end of palette
The alpha transparency, a number in [0,1], see argument alpha in
The (corrected) hue in [0,1] at which the color map begins.
Generate a discrete palette? (default:
generate continuous palette).
A character string indicating the color map option to use. Eight options are available:
"magma" (or "A")
"inferno" (or "B")
"plasma" (or "C")
"viridis" (or "D")
"cividis" (or "E")
"rocket" (or "F")
"mako" (or "G")
"turbo" (or "H")
