在构建程序包时，如何解决哪个函数负责无限递归？

Question

我正在构建一个小包，一切似乎运行良好，但在清理我的会话并使用devtools::load_all(".")重新加载包后，我收到以下错误消息：

Error: evaluation nested too deeply: infinite recursion / options(expressions=)?
In addition: Warning messages:
1: character(0) 
2: character(0) 
3: character(0) 
4: character(0) 
5: character(0) 
Error during wrapup: evaluation nested too deeply: infinite recursion / options(expressions=)?

如何找出导致无限循环的函数？
