Tree ring growth data in Json format for the development of logistic tree mortality models.

Json format is an easy-to-read textual representation of the experimental data. Data in Json format has great processing capabilities in R (https://www.r-project.org). R is a free software environment for statistical computing and graphics.

Initial data: Treedata.txt и RWdata.txt
Based on the initial data that are in the public domain (Cailleret et al., 2016), a data structure for tree ring increments in Json format and a converter program in the R programming language were developed.

Converter program:
Treedata.RWdata.to.json.R

Result:
TreeRWdata.json
The following data is defined for each tree:
Site- identifier of the tree's growing place, Species- short name of the species, Name- tree identifier, Article- link to the article, Contact- author, Old- tree age, be.sep- sign of tree status, Status- tree status values (1- live , 0- dead), Years- [year of birth of tree, year of sampling from tree or year of dried tree, DBH- diameter of tree at breast height (cm), Series- number of measurements of tree rings (mm)
