Dear all,
I have a vector with number that some of them are part of the
 
seq(1,800,4). How can I check which of the numbers belong to the seq(1,800,4)
 
LEt's say that is called myvector the vector with the numbers.
Is there in R something like this?
is.member(myvector,seq(1,800,4))
 
I would like to thank you in advance for your help
 
B.R
Alex
