Package: fvfmR Type: Package Title: Chlorophyll Fluorescence (Fv/Fm) Analysis of Leaf Disc Images Version: 1.0.0 Authors@R: c( person("Josef", "Garen", role = c("aut", "cph")), person("Pieter", "Arnold", role = c("aut", "cre", "cph"), email = "pieter.arnold@anu.edu.au"), person("Kristine", "Crous", role = c("aut", "cph")) ) Description: Semi-automated analysis of chlorophyll fluorescence images of leaf discs taken with a 'Walz' 'IMAGING-PAM' fluorometer. Provides an R interface to the 'fvfmPy' 'Python' package, which detects leaf discs, assigns them to a grid of rows and columns, and computes the maximum quantum efficiency of photosystem II, Fv/Fm = (Fm - Fo) / Fm, for each disc. The interactive 'fvfmPy' window is launched from R and the results are returned to R as a data frame.
