Two builds and two repositories

The repositories

I will keep from now on two CRAN-like repositories at this site. The one that has been in use for some time will remain in use, but I will only upload to it the stable and well tested versions of the packages.

I have just created a second repository with address R_test instead of R where I will keep the latest versions. This adds a slight complication, but will allow a smoother update process and give a more clear way of choosing the degree of novelty desired.

Releases at

Previews at (Path to repository updated on 7.01.2016!)

I have just uploaded to the “test” repository the result of recent weeks’ work and in particular the updates I did over the weekend to track the update of ggplot2 to version 2.0.0. Package photobiologygg has been replaced by a new package that I wrote over the weekend. The new is called ggspectra. I have re-implemented quite much of the functionality of the old package but there is still work to do on the waveband annotations which will become ggplot statistics. I have added a few new features to the stats I am re-writing which simplify their use, thanks to the improvements to package ggplot2. There are also quite a few improvements in ggplot2itself to facet labelling and even a couple of new geoms and stats have been added to version 2.0.0 of ggplot2. However, in the days since its release a few bugs have been found, and one of them interferes with the proper testing and to some extent use of the stats that I am writing, so if you can, wait a few days until ggplot2 2.0.1 is released. The problem I had was my own misunderstanding about how to create new ggplot statistics!

Future releases and previews

In posts, the released versions will be shown in blue as earlier, and the preview (=test) versions in orange, like this:

photobiology 0.9.0 (release: bug fix, new features)

Description of changes

NOTE: Sources, and Windows binaries for R 3.2.x, are now available in the R repository.

photobiology 0.9.1 (preview: bug fix, new features)

Description of changes

NOTE: Sources, and Windows binaries for R 3.2.x, are now available in the R-test repository.

Old repository at closed

For several months the main repository for the packages has been located at but the old repository remained available. From today the old repository has closed. So, if you were still using it, you will need to switch to the new address. Apart for their URL the repositories have been identical until a couple of weeks ago when I stopped updating the contents of the old repository.

All the photobiology packages updated

For some of the packages the updates are minor, just cosmetic changes to documentation. However, I have made some important changes to the “photobiology” package, and this has required me to also make changes to some packages that depend on it. The values returned by previously existing commands should remain unchanged, except for “photobiologySensors” where one previously incomplete data set has been replaced.
