Description Usage Arguments Value Examples

View source: R/plotLines.R

Plots an element's simulated atomic emission or atomic absorption line spectrum. The lines are taken from an object created using simulateAES. Atomic absorption spectra are displayed as a set of black lines superimposed on a background that shows the spectrum of visible electromagnetic radiation. Atomic emission spectra are displayed as set of lines, each of which has a color that matches its wavelength, superimosed on either a white or a black background.

  file,
  lambda.min = 390,

)

`file`	The name of an object, created by `simulateAES`, that contains the results of a simulation.
`lambda.min`	The minimum wavelength (in nm) for scaling the x-axis; defaults to 390 nm, which is the lower limit.
`lambda.max`	The maximum wavelength (in nm) for scaling the x-axis; defaults to 700 nm, which is the upper limit.
`spectrum_type`	Type of line spectrum, either `emission` or `absorbance`. Defaults to `emission`.
`emission_bg`	For an emission spectrum, choice of background color as `white` or `black`. Defaults to `white`.
`scale_emission`	Logical value that determines whether the transparency of an emission line is scaled to the emission line's relative intensity. Defaults to `FALSE`, which shows all emission lines regardless of intensity; emission lines of low intensity are too faint to see when `scale_emission` is set to `TRUE`. The value for `scale_emission` is ignored when plotting the element's absorbance spectrum.
`main_title`	An optional main title. If `NULL`, then a default title gives the element's atomic symbol, the temperature, and the partition model.

Returns a plot of the element's atomic emission line spectrum or the element's atomic absorption line spectrum.
