## 1.7 如何发问

The phrase “does not work” is not very helpful, it can mean quite a few things including:

• No explosion, but smoke is pouring out the back and microsoft’s “NoSmoke” utility is not compatible with your power supply.
• The computer stopped working.
• The computer sits around on the couch all day eating chips and watching talk shows.
• The computer has started picketing your house shouting catchy slogans and demanding better working conditions and an increase in memory.
• Everything went dark and you cannot check the cables on the back of the computer because the lights are off due to the power outage.
• R crashed, but the other programs are still working.
• R gave an error message and stopped processing your code after running for a while.
• R gave an error message without running any of your code (and is waiting for your next command).
• R is still running your code and the time has exceeded your patience so you think it has hung.
• R completed and returned a result, but also gave warnings.
