scales (version 0.2.3)

trans_new: Create a new transformation object.

Description

A transformation encapsulates a transformation and its inverse, as well as the information needed to create pleasing breaks and labels. The breaks function is applied on the transformed range of the range, and it's expected that the labels function will perform some kind of inverse tranformation on these breaks to give them labels that are meaningful on the original scale.

Usage

trans_new(name, transform, inverse,
    breaks = extended_breaks(), format = format_format(),
    domain = c(-Inf, Inf))

Arguments

name
transformation name
transform
function, or name of function, that performs the transformation
inverse
function, or name of function, that performs the inverse of the transformation
breaks
default breaks function for this transformation. The breaks function is applied to the raw data.
format
default format for this transformation. The format is applied to breaks generated to the raw data.
domain
domain, as numeric vector of length 2, over which transformation is valued
