Dear all,

I have a vector, and for each element I want to check whether it is equal to
any element from another vector. I want a vector of logical values with the
length of the first one as return. In R this would be :

> x <- 1:10
> sapply(x,function(y){any(y==c("2","3","4"))})
[1] FALSE  TRUE  TRUE  TRUE FALSE FALSE FALSE FALSE FALSE FALSE

It works pretty smooth, but I have the feeling there's a less complicated
way of doing it. My code should be readable by programmers who are not
really familiar with R, but I hate to use for-loops as I have pretty huge
datasets. Anybody an idea?
thank you in advance.

Cheers
Joris
