[R] compare multiple values with vector and return vector

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

Hi Joris Try Is.element function: is.element (x,y) Regards mohamed Joris Meys jorism...@gmail.com a écrit : 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

Re: [R] compare multiple values with vector and return vector

This was actually the one I was looking for, thx. It's actually essentially a wrapper for %in%, can't imagine I missed that one. I tried it out but I put the vectors in the wrong order (giving a vector of length 3). Guess it's too late to think clearly. Cheers On Sat, Apr 3, 2010 at 12:55 AM,
