R 4.0.1 and R 4.0.2

Two minor updates to R were released recently. R 4.0.1 contained a major bug under MS-Windows (affecting R-commander), so it was very soon followed by R 4.0.2 that fixes the problem. As always it is recommended to keep R up-to-date. R for photobiology packages and their dependencies are not affected and pass checks on R >= 3.6.0.

photobiologyFilters 0.5.0

The main changes from version 0.4.4, the current CRAN version, released 18 months ago are:

  • Code breaking! Names of some member spectra in the collection have been modified. In most cases, the change is the addition of the name of the supplier (e.g. filters.mspct$RG9 has become filters.mspct$Schott_RG9 ).
  • Rebuild data objects with current version of  ‘photobiology’ package (0.9.28).
  • Add data for MIDOPT filters released in the mean time.
  • Add data for an assortment photography filters of various brands.
  • Add data for the old “WG” UV pass filters from Schott, which have been replaced some years ago by “N-WG” filters.
  • Improve the metadata and documentation.

NOTE: The updated package is in CRAN.

Please raise issues concerning bugs or enhancements to this package through Bitbucket at https://bitbucket.org/aphalo/photobiologyfilters/issues

ggplot2 3.0.0

As the updated ‘ggplot2’ 3.0.0 became today available through CRAN, I will soon submit the new package ‘gginnards’ and a new enhanced version of package ‘ggpmisc’. That the first digit of the version of ‘ggplot2’ was increased reflects the fact that this is a major update to ‘ggplot2’ with some code breaking changes. The versions of packages ‘ggpmisc’ and ‘ggspectra’ now in CRAN are compatible with both ‘ggplot2’ 2.2.1 and 3.0.0. See https://ggplot2.tidyverse.org/ for details on ‘ggplot2’ updates.

 

ggpmisc roadmap

I am planning to split the ‘ggpmisc’ package into two separate packages for the next CRAN release. The low level functions and methods useful mainly to programmers will be transferred to a new package with possible name ‘ggpguts’ or ‘gginspector’. The remaining stats, geoms and scales, will remain in ‘ggpmisc’.
