资源简介:
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)

JSON格式是一种易于阅读的实验数据文本表示。在R语言(https://www.r-project.org)中,JSON格式的数据展现出卓越的处理能力。R是一种用于统计计算和图形的免费软件环境。
初始数据:Treedata.txt 和 RWdata.txt
基于公共领域内的初始数据(Cailleret等,2016年),开发了一种以JSON格式表示树木年轮增长数据的数据结构,以及一个R编程语言的转换程序。
转换程序:Treedata.RWdata.to..R
结果:TreeRWdata.
对于每棵树木,以下数据被定义:
位置标识符 - 树木生长地的标识符,物种 - 物种简称,名称 - 树木标识符,文章链接 - 文章的链接,联系人 - 作者,年龄 - 树木的年龄,be.sep - 树木状态的符号,状态 - 树木状态值(1-存活,0-死亡),年份 - [树木出生年份,从树木中采样年份或树木干燥年份,胸径 - 树木胸高直径(厘米),系列 - 树轮测量次数(毫米)]
