Hi all, say, I have following vector :
x <- c(rep(5, 5), rep(3,4), rep(5,10)) Now I want to get the index numbers where elements of that vector changes i.e. in above example I want to get a vector with elements : 6, 10. Because at that indices, element of original vector changes value. Is there any R function to do that?
