The package treenetproc cleans, processes and visualises highly
resolved time series of dendrometer data. In two steps, raw dendrometer
data is aligned to regular time intervals and cleaned.
Further, the package offers functions to extract the day of the year of the start and end of the growing season as well as several characteristics of shrinkage and expansion phases.
You can install the latest stable version of the package from GitHub with:
