使用非零状态码使 R 退出

发布于10月07日

我正在寻找linux/POSIX exit(n)的R类似功能，它将使用退出代码n停止进程，并向父进程发出发生错误的信号.R有这样的设施吗？

推荐答案

这是对quit()的辩论.见?quit.

Arguments:

status: the (numerical) error status to be returned to the operating
        system, where relevant.  Conventionally ‘0’ indicates
        successful completion.

Details:

 Some error statuses are used by R itself.  The default error
 handler for non-interactive use effectively calls ‘q("no", 1,
 FALSE)’ and returns error code 1.  Error status 2 is used for R
 ‘suicide’, that is a catastrophic failure, and other small numbers
 are used by specific ports for initialization failures.  It is
 recommended that users choose statuses of 10 or more.
