Three of my packages needed updates due to code-breaking changes introduced in ‘tidyr’ 1.0.0, an update which will soon be submitted to CRAN by its authors. I received warning e-mails only about ‘photobiologyInOut’, which I have updated and submitted to CRAN some time ago. More recently I have noticed that ‘ggspectra’ had also to be updated and this required an update to ‘photobiology’. ‘ggspectra’ 0.3.4 is ready to be submitted to CRAN as soon as ‘photobiology’ 0.9.29 is built on CRAN servers.
If you have been using ‘tidyr’ in your scripts, you may need to update them. The required edits are rather small but can come as a surprise, which is why I am writing this post.
The site has been updated to use encryption. For the web site, old addresses using http: are silently redirected to https:. If you have earlier received warnings from browsers because of the lack of encryption, this upgrade to the server settings should remove them.
The repository at the subdomain https://r.photobiology.info also supports encrypted connections. In addition, because of tightening of security in other ways, if you have been earlier using the address http://www.photobiology.info/R to access the repository, you will need to use https://r.photobiology.info instead from now on. In other words if you are setting this repository address in an .Rprofile file you should edit it to use the new address.
The documentation should be accessed through https://docs.photobiology.info as settings for this subdomain have been changing in the same way.
All these changes should ensure enhanced security for the site and downloads.
R 3.5.0 was released on 23 April. It includes several performance improvements. All packages in the ‘r4photobiology’ suite pass checks on the new version. In CRAN binaries for R 3.5.0 of all packages have been built. In the case of development versions and packages not in CRAN, the repository at http://r.r4photobiology.info/ will soon be updated to include binaries suitable for R 3.5.0. Meanwhile packages will be installed from sources if the require tools are available (e.g. RTools 3.5.0 or 3.4.0 installed in Windows computers).
The update from R 3.4.x to R 3.5.x requires that all packages are reinstalled. For the time being avoid using package ‘installr’ to do the update, at least on Windows, as copying installed packages from an earlier installation is not useful. Please see the page Upgrading Rfor instructions.
