Absorbance y-scale

Source: R/axis-utils-filter-spct.R
scale_y_A_continuous.Rd

Scale y continuous with defaults suitable for spectral absorbance.

Usage

scale_y_A_continuous(
  unit.exponent = 0,
  name = A_label(unit.exponent = unit.exponent, format = format, label.text = label.text,
    scaled = scaled, normalized = ifelse(is.numeric(normalized), round(normalized, 1),
    unique(normalized)), axis.symbols = axis.symbols, Tfr.type = Tfr.type),
  labels = SI_pl_format(exponent = unit.exponent),
  format = getOption("photobiology.math", default = "R.expression"),
  label.text = NULL,
  scaled = FALSE,
  normalized = FALSE,
  axis.symbols = getOption("ggspectra.axis.symbols", default = TRUE),
  Tfr.type,
  ...
)

scale_y_A_internal_continuous(
  unit.exponent = 0,
  name = A_label(unit.exponent = unit.exponent, format = format, label.text = label.text,
    scaled = scaled, normalized = ifelse(is.numeric(normalized), round(normalized, 1),
    unique(normalized)), axis.symbols = axis.symbols, Tfr.type = "internal"),
  labels = SI_pl_format(exponent = unit.exponent),
  format = getOption("photobiology.math", default = "R.expression"),
  label.text = NULL,
  scaled = FALSE,
  normalized = FALSE,
  axis.symbols = getOption("ggspectra.axis.symbols", default = TRUE),
  ...
)

scale_y_A_total_continuous(
  unit.exponent = 0,
  name = A_label(unit.exponent = unit.exponent, format = format, label.text = label.text,
    scaled = scaled, normalized = ifelse(is.numeric(normalized), round(normalized, 1),
    unique(normalized)), axis.symbols = axis.symbols, Tfr.type = "total"),
  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.

format

character string, "R", "R.expression", "R.character", or "LaTeX".

label.text

character Textual portion of the labels.

scaled

logical If TRUE relative units are assumed.

normalized

logical (FALSE) or numeric Normalization wavelength in manometers (nm).

axis.symbols

logical If TRUE symbols of the quantities are added to the name. Supported only by format = "R.expression".

Tfr.type

character, either "total" or "internal".

...

other named arguments passed to scale_y_continuous

Note

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