Tools for downloading and extracting data from the Copernicus "Agrometeorological indicators

Calculate 'ActiGraph' counts from the X, Y, and Z axes of a triaxial 
    accelerometer. This work was inspired by Neishabouri et al. who published the 
    article "Quantification of Acceleration as Activity Counts in 'ActiGraph' Wearables" 
    on February 24, 2022. The link to the article (<https://pubmed.ncbi.nlm.nih.gov/35831446>) 
    and 'python' implementation of this code (<https://github.com/actigraph/agcounts>).

Tools for the analysis of growth data: to extract an 
    LMS table from a gamlss object, to calculate the standard 
    deviation scores and its inverse, and to superpose two wormplots 
    from different models. The package contains a some varieties of 
    reference tables, especially for The Netherlands.

Implements the Age Band Decomposition (ABD) method for 
 standardizing tree ring width data while preserving both low and high frequency 
 variability. Unlike traditional detrending approaches that can distort long term 
 growth trends, ABD decomposes ring width series into multiple age classes, detrends 
 each class separately, and then recombines them to create standardized chronologies. 
 This approach improves the detection of growth signals linked to past climatic and 
 environmental factors, making it particularly valuable for dendroecological and 
 dendroclimatological studies. The package provides functions to perform ABD-based 
 standardization, compare results with other common methods (e.g., BAI, C method, RCS), 
 and facilitate the interpretation of growth patterns under current and future climate 
 variability.

Pair of simple convenience functions to convert a vector of birth dates to age and age distributions. These functions may be helpful when related age and custom age distributions are desired given a vector of birth dates.
