R 中mtcars"数据集中的vs"变量是什么意思?帮助文件说它的意思是V/S"，但这并不具有启发性.

What does the "vs" variable mean in the "mtcars" dataset in R? The helpfile says it means "V/S" but that is not enlightening.

命令:

data(mtcars)
head(mtcars)
?mtcars

推荐答案

我觉得是车有没有V引擎 或 直接引擎.我基于 http://www 的第 396 页的脚注.mortality.org/INdb/2008/02/12/8/document.pdf

I think it's whether the car has a V engine or a straight engine. I'm basing this on the foot note on the page numered 396 of http://www.mortality.org/INdb/2008/02/12/8/document.pdf
