Plot Spectroscopic Profile with ggplot2 — qplotc • hySpc.ggplot2

This function plots spectroscopic concenration, depth, time-series, etc. profiles by using ggplot2.

Note: The function is still experimental and may change in the future.

qplotc(
  object,
  mapping = aes_string(x = "c", y = "spc"),
  ...,
  func = NULL,
  func.args = list(),
  map.pointonly = FALSE
)

Arguments

object: A hyperSpec object.
mapping: See ggplot2::geom_point().
...: Further arguments handed to ggplot2::geom_point().
func: Function to summarize the wavelengths. If NULL, only the first wavelength is used.
func.args: A named list with arguments to func.
map.pointonly: If TRUE, mapping will be handed to ggplot2::geom_point() instead of ggplot2::ggplot().

Value

A ggplot2::ggplot() object.
