Rstudio 的控制台在交互模式测试时卡住了
Rstudio's console stuck while interactive mode testing
我尝试在 Rstudio 中测试交互模式：
ans <- readLines("stdin", n = 1)
print(ans)
但是控制台卡住了，不接受任何命令。在那之后我什至无法退出这种模式，不得不重新启动整个 Rstudio。
我做错了什么？
从 stdin() 读取，而不是 file("stdin"):
ans <- readLines(stdin(), n = 1)
来自 ?stdin:
stdin() refers to the 'console' and not to the C-level stdin of the process. The distinction matters in GUI consoles (which may not have an active stdin, and if they do it may not be connected to console input), and also in embedded applications. If you want access to the C-level file stream stdin, use file("stdin").
