qplotspc: Spectra plotting with ggplot2

Description

Spectra plotting with ggplot2

Usage

qplotspc(x, wl.range = TRUE, ..., mapping = aes_string(x = ".wavelength", y
  = "spc", group = ".rownames"), spc.nmax = hy.getOption("ggplot.spc.nmax"),
  map.lineonly = FALSE, debuglevel = hy.getOption("debuglevel"))

Arguments

x

hyperSpec object

wl.range

wavelength ranges to plot

...

handed to geom_line

mapping

see geom_line

spc.nmax

maximum number of spectra to plot

map.lineonly

if TRUE, mapping will be handed to geom_line instead of ggplot.

debuglevel

if > 0, additional debug output is produced

Value

a ggplot object

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