Arguments
aesthetics
the names of the aesthetics that this scale works with

  • a character vector giving the breaks as they should appear on the axis or in the legend.
  • waiver()
labels
NULL for no labels, waiver() for default labels (labels the same as breaks), a character vector the same length as breaks, or a named character vector whose names are used to match replacement the labels for matching breaks.
legend
deprecated. Use guide instead.
limits
A character vector specifying the data range for the scale. and the default order of their display in guides.
expand
a numeric vector of length two, giving a multiplicative and additive constant used to expand the range of the scales so that there is a small gap between the data and the axes.
