Arguments

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 object A 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()`)
minor_breaks	One of: `NULL` for no minor breaks `waiver()` 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.
n.breaks	An integer guiding the number of major breaks. The algorithm may choose a slightly different number to ensure nice break labels. Will only have an effect if `breaks = waiver()`. Use `NULL` to use the default number of breaks given by the transformation.
labels	One of: `NULL` for no labels `waiver()` for the default labels computed by the transformation object A 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 range A numeric vector of length two providing limits of the scale. Use `NA` to refer to the existing minimum or maximum A 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.
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()`.
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
