```

aesthetics

The names of the aesthetics that this scale works with.

scale_name

The name of the scale that should be used for error messages associated with this scale.

palette

A palette function that when called with a numeric vector with
values between 0 and 1 returns the corresponding output values
(e.g., `scales::area_pal()`

).

name

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
omitted.

breaks

One of:

`NULL`

for no breaks`waiver()`

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()`

)

labels

One of:

`NULL`

for no labels`waiver()`

for the default labels computed by the transformation objectA character vector giving labels (must be same length as

`breaks`

)A function that takes the breaks as input and returns labels as output

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 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()`

).

rescaler

A function used to scale the input values to the
range [0, 1]. This is always `scales::rescale()`

, except for
diverging and n colour gradients (i.e., `scale_colour_gradient2()`

,
`scale_colour_gradientn()`

). The `rescaler`

is ignored by position
scales, which always use `scales::rescale()`

.

oob

One of:

Function that handles limits outside of the scale limits (out of bounds).

The default (

`scales::censor()`

) replaces out of bounds values with`NA`

.`scales::squish()`

for squishing out of bounds values into range.`scales::squish_infinite()`

for squishing infinite values into range.

expand

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 `expansion()`

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.

na.value

Missing values will be replaced with this value.

n.breaks

The number of break points to create if breaks are not given directly.

nice.breaks

Logical. Should breaks be attempted placed at nice values
instead of exactly evenly spaced between the limits. If `TRUE`

(default)
the scale will ask the transformation object to create breaks, and this
may result in a different number of breaks than requested. Ignored if
breaks are given explicetly.

right

Should values on the border between bins be part of the right (upper) bin?

trans

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 `<name>_trans`

(e.g.,
`scales::boxcox_trans()`

). You can create your own
transformation with `scales::trans_new()`

.

show.limits

should the limits of the scale appear as ticks

guide

A function used to create a guide or its name. See
`guides()`

for more information.

position

For position scales, The position of the axis.
`left`

or `right`

for y axes, `top`

or `bottom`

for x axes.

super

The super class to use for the constructed scale
