[R] How do I use the proper r code to find the value of intersection (What horsepower(hp) does the “Valiant” have?)

[François Morneau]

Hello (Who?),

Perhaps should you try to do your homework, look at "An Introduction to
R" for example and read the help pages :

> ?intersect # is clearly not what your are looking for
> ?'[' # seems better
and you would have find that :
> mtcars["Valiant", "hp"] # is one way to get what you are looking for.

You should also have a look at :

> library(fortunes)
> fortune(122)

Regards,

François
