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.https://github.com/r-universe/garenj/actions/runs/39017993927Wed, 07 Oct 2026 04:39:59 GMTfvfmR1.0.0successhttps://garenj.r-universe.devhttps://github.com/garenj/fvfmr
