plotSpecMat Overlaid/Stacked Plot
plotSpecMat Plot spectra set, overlaid or stacked; if stacked, plot with or
without a perspective effect.
plotSpecMat(specMat, ppm_lim = c(min(specMat$ppm), max(specMat$ppm)), K = 0.67, pY = 1, dppm_max = 0.2 * (max(ppm_lim) - min(ppm_lim)), asym = 1, beta = 0, cols = NULL)
specMat |
a 'specMat' object - Spectra matrix in specMat$int (rows = samples, columns = buckets) |
ppm_lim |
ppm range of the plot |
K |
Graphical height of the stack (0 .. 1),(default=0.67) |
pY |
Intensity limit factor (default 1) |
dppm_max |
Max ppm shift to have a perspective effect |
asym |
Correction of vertical parallax effect (-1 .. 1) -1 : parallelogram 0 : trapeze with maximum asymmetric 1 : symmetric trapeze |
beta |
Correction of horizontal parallax effect (0 .. 0.2) (defaut 0) |
cols |
Vector of colors (same size that the number of spectra, i.e dim(specmat)[1]) |
