Arguments
- ...
Arguments passed on to
continuous_scale
minor_breaks
One of:
NULL
for no minor breakswaiver()
for the default breaks (one minor break between each major break)A numeric vector of positions
A function that given the limits returns a vector of minor breaks. Also accepts rlang lambda function notation. When the function has two arguments, it will be given the limits and major breaks.
oob
One of:
Function that handles limits outside of the scale limits (out of bounds). Also accepts rlang lambda function notation.
The default (
scales::censor()
) replaces out of bounds values withNA
.scales::squish()
for squishing out of bounds values into range.scales::squish_infinite()
for squishing infinite values into range.
na.value
Missing values will be replaced with this value.
call
The
call
used to construct the scale for reporting messages.super
The super class to use for the constructed scale
- aesthetics
Character string or vector of character strings listing the name(s) of the aesthetic(s) that this scale works with. This can be useful, for example, to apply colour settings to the colour and fill aesthetics at the same time, via aesthetics = c("colour", "fill").
- guide
Type of legend. Use "colourbar" for continuous colour bar, or "legend" for discrete colour legend.
- range
Output range of alpha values. Must lie between 0 and 1.
- breaks
One of:
NULL
for no breakswaiver()
for the default breaks computed by the transformation objectA numeric vector of positions
A function that takes the limits as input and returns breaks as output (e.g., a function returned by
scales::extended_breaks()
). Note that for position scales, limits are provided after scale expansion. Also accepts rlang lambda function notation.
- labels
One of:
NULL
for no labelswaiver()
for the default labels computed by the transformation objectA character vector giving labels (must be same length as
breaks
)An expression vector (must be the same length as breaks). See ?plotmath for details.
A function that takes the breaks as input and returns labels as output. Also accepts rlang lambda function notation.
- limits
One of:
NULL
to use the default scale rangeA numeric vector of length two providing limits of the scale. Use
NA
to refer to the existing minimum or maximumA function that accepts the existing (automatic) limits and returns new limits. Also accepts rlang lambda function notation. Note that setting limits on positional scales will remove data outside of the limits. If the purpose is to zoom, use the limit argument in the coordinate system (see
coord_cartesian()
).
- transform
For continuous scales, the name of a transformation object or the object itself. Built-in transformations include "asn", "atanh", "boxcox", "date", "exp", "hms", "identity", "log", "log10", "log1p", "log2", "logit", "modulus", "probability", "probit", "pseudo_log", "reciprocal", "reverse", "sqrt" and "time".
A transformation object bundles together a transform, its inverse, and methods for generating breaks and labels. Transformation objects are defined in the scales package, and are called
transform_<name>
. If transformations require arguments, you can call them from the scales package, e.g.scales::transform_boxcox(p = 2)
. You can create your own transformation withscales::new_transform()
.
