写在前面

- 使用的是Rstudio

- 其实R已经有生成sdtm相关的package，以下代码仅作为练习R语言的语法，不是高效生成sdtm的方法

- 代码中没有解决的问题包括：EPOCH相关的逻辑没有考虑partial date的情况；在使用arrange() function做-SEQ排序时，关于大小写英文字母的排序机制似乎与SAS语言的sort function有所不同，导致使用相同的排序变量，通过R和SAS排序后，record的顺序会有不同；输出xpt结果是乱码，暂时输出到csv文件中。

- 还没有写生成SUPPAE的代码

- 代码参考了以下材料

Generating .xpt files with SAS, R and Python
