Continuous scale constructor.

Continuous scale constructor.

continuous_scale(aesthetics, scale_name, palette, name = waiver(),
  breaks = waiver(), minor_breaks = waiver(), labels = waiver(),
  limits = NULL, rescaler = rescale, oob = censor,
  expand = waiver(), na.value = NA_real_, trans = "identity",
  guide = "legend", position = "left", super = ScaleContinuous)

Arguments

aesthetics	The names of the aesthetics that this scale works with
scale_name	The name of the scale
palette	A palette function that when called with a numeric vector with values between 0 and 1 returns the corresponding values in the range the scale maps to.
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
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.
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
rescaler	Used by diverging and n colour gradients (i.e. scale_colour_gradient2(), scale_colour_gradientn()). A function used to scale the input values to the range [0, 1].
oob	Function that handles limits outside of the scale limits (out of bounds). The default replaces out of bounds values with NA.
expand	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 expand_scale() 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	Either 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 info.
position	The position of the axis. "left" or "right" for vertical scales, "top" or "bottom" for horizontal scales
super	The super class to use for the constructed scale
