StemAnalysis: An R-package for reconstructing tree growth and carbon accumulation with stem analysis data.

•StemAnalysis package can optionally perform several tasks for any tree species.•Age class determination is a useful approach to address field plague.•The growth trends of outside-bark diameter for a given tree are calculated.•Tree biomass and carbon storage estimated by volume and allometric models.•Height-diameter relationship is fitted with nonlinear models in this package.
