Raw-counts axis labels — counts

Generate axis labels in SI units, using SI scale factors. Output can be selected as character, expression (R default devices) or LaTeX (for tikz device).

Usage

counts_label(
  unit.exponent = 3,
  format = getOption("photobiology.math", default = "R.expression"),
  label.text = axis_labels(append = ifelse(axis.symbols, ",", ""))[["counts"]],
  scaled = FALSE,
  normalized = FALSE,
  axis.symbols = getOption("ggspectra.axis.symbols", default = TRUE)
)

Arguments

unit.exponent: integer
format: character string, "R", "R.expresion", "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".

Value

a character string or an R expression.

Examples


counts_label()
#> "Pixel response," ~ italic(N)[lambda] ~ (10^{
#>     3
#> } * plain(counts))
counts_label("R.expression")
#> "Pixel response," ~ italic(N)[lambda] ~ (10^{
#>     "R.expression"
#> } * plain(counts))
counts_label("LaTeX")
#> "Pixel response," ~ italic(N)[lambda] ~ (10^{
#>     "LaTeX"
#> } * plain(counts))
