Pretty breaks on transformed scale

Description

These often do not produce very attractive breaks.

Usage

trans_breaks(trans, inv, n = 5, ...)

Arguments

trans	function of single variable, x, that given a numeric vector returns the transformed values
inv	inverse of the transformation function
n	desired number of ticks
...	other arguments passed on to pretty

Examples

trans_breaks("log10", function(x) 10^x)(c(1, 1e6))
trans_breaks("sqrt", function(x) x^2)(c(1, 100))
trans_breaks(function(x) 1 / x, function(x) 1 / x)(c(1, 100))
trans_breaks(function(x) -x, function(x) -x)(c(1, 100))
