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 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.
