R: Absorbance y-scale

scale_y_A_internal_continuous {ggspectra} | R Documentation

## Absorbance y-scale

### Description

Scale y continuous with defaults suitable for spectral absorbance.

### Usage

    scale_y_A_internal_continuous(unit.exponent = 0,
      name = A_internal_label(unit.exponent = unit.exponent),
      labels = SI_pl_format(exponent = unit.exponent), ...)

    scale_y_A_total_continuous(unit.exponent = 0,
      name = A_total_label(unit.exponent = unit.exponent),
      labels = SI_pl_format(exponent = unit.exponent), ...)

### Arguments

`unit.exponent` | integer
`name` | The name of the scale, used for the axis-label.
`labels` | The tick labels or a function to generate them.
`...` | other named arguments passed to `scale_y_continuous`

### Note

This function only alters two default arguments, please, see documentation for `scale_continuous`

### Examples

    library(ggplot2)
    library(photobiology)

    ggplot(yellow_gel.spct, plot.qty = "absorbance") +
      geom_line() +
      scale_y_A_internal_continuous() +
