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

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

Details

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

Value

a ggplot object

Examples

  qplotspc (chondro)

  qplotspc (paracetamol, c (2800 ~ max, min ~ 1800)) + scale_x_reverse (breaks = seq (0, 3200, 400))

  qplotspc (aggregate (chondro, chondro$clusters, mean),
            mapping = aes (x = .wavelength, y = spc, colour = clusters)) +
    facet_grid (clusters ~ .)

  qplotspc (aggregate (chondro, chondro$clusters, mean_pm_sd),
            mapping = aes (x = .wavelength, y = spc, colour = clusters, group = .rownames)) +
    facet_grid (clusters ~ .)
