Continuous scale constructor
continuous_scale( aesthetics, scale_name, palette, name = waiver(), breaks = waiver(), minor_breaks = waiver(), n.breaks = NULL, labels = waiver(), limits = NULL, rescaler = rescale, oob = censor, expand = waiver(), na.value = NA_real_, trans = "identity", guide = "legend", position = "left", super = ScaleContinuous )
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., 
name  The name of the scale. Used as the axis or legend title. If

breaks  One of:

minor_breaks  One of:

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 
labels  One of:

limits  One of:

rescaler  A function used to scale the input values to the
range [0, 1]. This is always 
oob  One of:

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 
na.value  Missing values will be replaced with this value. 
trans  For continuous scales, the name of a transformation object or the object itself. Builtin 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 
guide  A function used to create a guide or its name. See

position  For position scales, The position of the axis.

super  The super class to use for the constructed scale
