About the Book
This handbook describes how to use R as a tool for doing calculations related to research in photobiology. Photobiology is the branch of science that studies the interactions of living organisms with visible and ultraviolet radiation. Many of the most frequently used calculations are either related to the characterization of radiation and of the responses of organisms to radiation. We emphasize the first of these aspects related to radiation quantification and the position of the sun. These include acquisition, processing and summarising of spectral data including the calculation of non-weighted and biologically effective exposures. Calculations related to interactions of radiation with inanimate objects and organisms are also treated in detail.
The text and examples assume some familiarity with R and/or programming, but guides those readers new to the language to tutorials and books that will help them learn enough to follow, use and modify the code examples included in the book. The book is structured in five parts: I Theory behind calculations, II Tools used for calculations, III Cookbook of calculations, IV Data acquisition and exchange and V Catalogue of example data.
In most of the examples we use of a suite of R packages developed by Pedro J. Aphalo and described at http://www.r4photobiology.info/. At the moment the ten most important packages in the suite are available through CRAN and the few remaining ones through a CRAN-like repository at http://r.r4photobiology.info/.
