Package installation simplified. I have created a “CRAN-style” repository for distributing the packages. This makes installation and updates much simpler. Please see the new page with instructions.
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.
