trans_breaks {scales} | R Documentation

## 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))
