Note:

Package hyperSpec and it’s friends provide a number of vignettes to help you get started.

• You can access the vignettes via these links:

  • Introduction to hyperSpec
  • Plotting Functions in hyperSpec
  • Fitting Baselines to Spectra
  • Importing Files into hyperSpec
  • flu: Example Workflow for Fluorescene Emission
  • laser: Example Workflow for Spectral Time Series

• Alternatively, if you are offline or prefer accessing the vignettes with R, simply type browseVignettes("hyperSpec") to get a clickable list in a browser window.

• Vignettes in other packages:

  • Example Workflow for 2D Raman Spectra (chondro dataset)
  • Plotting hyperSpec objects with ggplot2
  • Using dplyr functions with hyperSpec objects
