R-Markdown script used for statistical analysis and graphics generation.

Zip file containing several files necessary to replicate the statistical analysis and generation of graphics. Besides some external tables, an R-function file, and three pictures to mark the respective experiment in graphs, the zip file consists of nine R-Markdown scripts. One of these is used to set up the data prior to analysis. The necessary data can be downloaded from the Open Science Framework [39]. Five of the R-Markdown files are for analysis of Experiment I, II, III Short, III Long, and the pooled data. The eighth file is for graphics generation. The second-to-last file takes a sample of ten random participants from the first experiment for every protocol and builds the base model from this subset. This sample analysis is to show that the main dependencies of wavelength and series can come from a smaller sample. An html file with the same file name shows an example. The last file is for calculating estimates for prereceptoral filtering and using those estimates to calculate irradiance and photon density values from the spectral irradiance measurements. (ZIP)
