Analysis of Chlorophyll a Fluorescence Transient Parameters R package fluorojip version 0.1.1 Computes chlorophyll a fluorescence transient parameters from fluorescence summary data, including minimum and maximum fluorescence, selected transient steps, and area. Provides standard photosynthetic performance indices and fluxes per reaction center and per cross section. Includes helpers to read exported trace tables in supported 'csv' formats and validation workflows based on bundled example files, as well as visualization tools and an interactive 'shiny' interface. The implemented calculations are based on Strasser et al. (2004) <doi:10.1007/978-1-4020-3218-9_12> and Stirbet and Govindjee (2011) <doi:10.1016/j.jphotobiol.2010.12.010>.
