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

Comfortable ways to work with hyperspectral data sets. I.e. spatially or time-resolved spectra, or spectra with any other kind of information associated with each of the spectra. The spectra can be data as obtained in XRF, UV/VIS, Fluorescence, AES, NIR, IR, Raman, NMR, MS, etc. More generally, any data that is recorded over a discretized variable, e.g. absorbance = f (wavelength), stored as a vector of absorbance values for discrete wavelengths is suitable.

FUNCTIONALITY:

o plotc is now a lattice function

o plotc and plotmap gained a standard formula interface

o plotvoronoi is an alternative to plotmap for non-rectangularly spaced grids

o plot (x, "mat") is an abbreviation to plot the spectra matrix

o The special handling of MARGINS in apply changed to be more consistent with standard behaviour apply (x, 1 : 2, FUN, ...) is now calling FUN for each element of the spectra matrix, and apply (x, , FUN, ...) calls FUN with the complete spectra matrix.

o hyperSpec now reads the binary file formats .spc as well as ENVI files.
There are two specialized functions to import Nicolet FTIR Images (ENVI) and Kaiser Raman maps (spc)

o collapse rbinds a list of hyperSpec object that may have different wavelength axes

o a more general way to combine two hyperSpec objects is merge.

DOCUMENTATION:

o Plotting functions are discussed in a separate vignette "plotting" now

o Import- and Export functions for diverse file formats are discussed in vignette "fileio"
