photobiology 0.10.4

Package documentation web site at: https://docs.r4photobiology.info/photobiology/

This release was triggered by a bug that made the package fail CRAN checks with an ERROR.

Changes from version 0.10.3 the most recent CRAN release, are:

New

  • Improve performance of color-related computations.

Fixed

  • Bugs affecting boundary cases in the new color related functions.
  • Bad code in one example in documentation. This was causing ERRORs to be reported in CRAN checks.

NOTE: The updated package is on its way to CRAN.

photobiology 0.10.3

Package documentation web site at: https://docs.r4photobiology.info/photobiology/

This release was triggered by problems detected by new tighter CRAN checks in what will become R (4.1.0). Better quality checks are a good thing! A few unrelated enhancements are also included.

Changes from version 0.10.2 the most recent CRAN release, are:

New

  • Implement Fresnel’s formulae for computation of reflectance of a plane interface from relative refractive index.
  • Implement Fraunhofer’s formulae for computation of diffraction in a single slit and diffraction plus interference in a double slit.
  • Enhance as_tod() and implement format() and print() methods for time-of-day.
  • Update tag() methods to use, when possible, precomputed color definitions to improve performance.

Fixed

  • Handle gracefully bad data input in normalised_diff_ind().
  • Remove bad class exports from NAMESPACE.

Compatibility

  • New features of ‘dplyr’ (>= 1.0.0) are used, so this new version is required.

NOTE: The updated package is on its way to CRAN.

The main changes from version 0.4.3 the previous CRAN release, are:

New

  • NDVI() for computing the Normalized Difference Vegetation Index from spectral transmitance.

Fixed

  • Avoid warnings during building of vignettes, caused by changes to the options recognized by ‘roxygen2’.
  • Update URLs to secure ones if available.

NOTE: The updated package is on its way to CRAN.
