R-script and Data for STOTEN-D-21-08485

Here are the R-script and data we used for main analyses and Figures in our paper STOTEN-D-21-08485 "Contrasting life-history traits of black spruce and jack pine influence their physiological response to drought and growth recovery in northeastern boreal Canada"<br>Code for supplementary figures was not provided here, except for the PCA analysis. However, these Supplementary figures can be easily obtained by simply switching variables in statistical models and the corresponding ggplot script. <br>Only processed data is provided. If needed, raw data could be obtained upon request to [e-mail] (for C isotope data; raw 18O isotope data are provided as they are used for supplementary figures) and [e-mail] (for tree-ring data; that is part of a provincial forest inventory database).<br>Importantly, please note that a few random noise was added to plot coordinates. This was done because these plots are part of a forest inventory network, and the provincial agencies in charge of the database want to keep plot coordinates confidential.

本研究论文STOTEN-D-21-08485《加拿大东北部北方针叶林黑云杉与北美短叶松的生活史特征差异对其干旱生理响应与生长恢复的影响》中，用于核心分析与所有配图的R脚本及数据集如下：
除主成分分析（PCA）代码外，本数据集未附带补充图表的生成代码。但仅需调整统计模型中的变量，并调用对应的ggplot脚本，即可轻松复现所有补充图表。
本数据集仅提供预处理后的数据。若需原始数据，可通过以下邮箱申请获取：致[e-mail]（用于碳同位素数据；原始18O同位素数据已随附，因其用于补充图表制作）；致[e-mail]（用于树木年轮数据，该数据隶属于省级森林资源清查数据库）。
重要提示：本数据集已向样地坐标添加少量随机噪声。此举因上述样地隶属于省级森林清查网络，负责管理该数据库的省级机构要求对样地原始坐标予以保密。
