命令行问题 [英] Command line Questions in R

问题描述

我正在R中建立一个用户输入界面。

I am building an user input interface in R.

程序的加载，我想询问用户他们的偏好是根据一组6个字段。

onload of the program, I would like like to ask the user what their preferences are according to a set of 6 fields. This will then be used as a comparison tool for the rest of the program.

例如

>ThisProgram  
>"Hello, on a scale of 1 to 10, how much would you say you rate the outdoors in your trips?    Enter a 10 for very important, and a 1 for not important at all.   
>7  
>"Great. on a scale of 1 to 10, how much would you say you rate the Family Friendly in your  trips?  Enter a 10 for very important, and a 1 for not important at all. 
>2
  .
  .
  .
  and so on...

我如何得到R问用户一个问题，然后将响应存储在向量中？

how would I get R to ask the user a question, and then store the response in a vector?

推荐答案

请参阅？readline

> x <- readline("What is your name? ")
What is your name? Josh
> x
[1] "Josh"
