In hyperSpec: Work with Hyperspectral Data, i.e. Spectra + Meta Information (Spatial, Time, Concentration, ...)

Description

Spectra plotting with ggplot2

Usage

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

Arguments

object	hyperSpec object
mapping	see geom_point
...	handed to geom_point
func	function to summarize the wavelengths, if NULL, only the first wavelength is used
func.args	arguments to func
map.pointonly	if TRUE, mapping will be handed to geom_point instead of ggplot.

Details

These functions are still experimental and may change substantially in future.

Value
