使R退出非零状态代码

Question

我正在寻找R /等效的linux/POSIX exit(n),它将使用退出代码n停止进程,向父进程发出错误信号.R有这样的设施吗？

Answer 1

这是一个论据quit().见?quit.

参数:

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

细节:

 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.

Answer 2

quit(status=1)
