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  http://www.r4photobiology.info/R

Previews at http://www.r4photobiology.info/R-test (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 Package photobiologygg has been replaced by a new package that I wrote over the weekend.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!
