Aims and scope

The aim of this blog is to publish content related to the use of R, the environment for data analysis and the scripting and programing language, in the analysis and acquisition of data from the field of photobiology. We take a very broad view of photobiology, so anything useful to a photobiologist is within scope. This includes analysis of data that is in the realm of radiation meteorology and climatology, and even geophysics. Contributions from anybody are warmly welcome, but acceptance is at the discretion of the editor.

In addition, this blog is the home of software written Pedro J. Aphalo, using the Gnu S programming languages. The different R packages implement calculations related to handling of spectral data as used in photobiology. The main purpose of this software is to make it easier for biologists to quantify and describe the visible and ultraviolet radiation conditions used in experiments or monitored in nature, in a standardized and consistent way. In accordance with the ideas of “repeatable science” all the code is open-software and all algorithms and data used, unless original, are linked to the original sources. The code is fully commented and written using consistent naming conventions and a consistent formatting style. The packages are fully documented and include usage examples for all functions. Documentation follows standard R documentation practices, and includes several vignettes, including user manuals. The packages should be compatible with Windows (x86/x64), Linux (x86/x64), and OS X. Testing has been done under Ubuntu (64 bit)  and Windows (32/64 bit), except for those packages in CRAN which have been tested as part of the submission process in all R platforms.

The packages have been designed trying to make code maintenance as simple and as reliable as possible.

Furthermore, a central aim of the design has been to allow the easy implementation of additional ways of quantifying radiation by users, who will hopefully contribute them back to this project so that this family of packages with time caters for all aspects of photobiology.

The latest source code and all earlier versions are available from git repositories at https://bitbucket.org/aphalo/
