%description
Data management and cleaning for dendrometer and sap flux data, including
gap detection, NA identification, missing value interpolation, and date
conversion. The package also calculates multiple growth metrics of tree
radial change data, including the cumulative growth over the entire
observation period, daily cumulative growth, and growth changes between
adjacent time intervals. Various approaches can be applied to calculate
the night delta-Tmax required for sap flow (Peters et al., 2018,
<doi:10.1111/nph.15241>) and subsequently estimate sap flow density
(Granier, 1987, <doi:10.1093/treephys/3.4.309>). In addition, it supports
the creation of simple time‑series point plots to visually display the
dynamic changes in tree growth status or sap flow density during that
period.
