R: Wavelength x-scale

scale_x_wl_continuous {ggspectra}

R Documentation

Wavelength x-scale

Description

Scale x continuous with defaults suitable for wavelengths in nanometres.

Usage

scale_x_wl_continuous(unit.exponent = -9,
  name = w_length_label(unit.exponent = unit.exponent),
  breaks = scales::pretty_breaks(n = 7), labels = SI_pl_format(exponent =
  unit.exponent + 9), ...)

Arguments

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

Note

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