Examples

  #  generate example 
 exampleSpectra     <-  getSpectraInTimeCompExample()

  # methods
     PCAResult      <-  getDimensionReduction( exampleSpectra, type = "PCA" )
     NMFResult      <-  getDimensionReduction( exampleSpectra, type = "NMF" )
     
     dimensionReductions  <-  getDimensionReduction( exampleSpectra )
     str(dimensionReductions  )

  # subsetting works by reducing to \code{\link{SpectraInTime-class}}
  subsetting     <-  exampleSpectra[1:3 , r(400, 450)]
  # preprocessing methods also reduce the object to \code{\link{SpectraInTime-class}}
