Usage
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")
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 single integer argument (the number of levels in the scale) returns the values that they should take
 name
 The name of the scale. Used as axis or legend title. If
NULL
, the default, the name of the scale is taken from the first mapping used for that aesthetic.  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
 A numeric vector of length two providing limits of the scale.
Use
NA
to refer to the existing minimum or maximum.  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
 A numeric vector of length two giving multiplicative and
additive expansion constants. These constants ensure that the data is
placed some distance away from the axes. The defaults are
c(0.05, 0)
for continuous variables, andc(0, 0.6)
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. Builtin transformations include "asn", "atanh",
"boxcox", "exp", "identity", "log", "log10", "log1p", "log2",
"logit", "probability", "probit", "reciprocal", "reverse" and "sqrt".
A transformation object bundles together a transform, it's inverse, and methods for generating breaks and labels. Transformation objects are defined in the scales package, and are called
name_trans
, e.g.boxcox_trans
. You can create your own transformation withtrans_new
.  guide
 Name of guide object, or object itself.
