Dear list members,
I am seeking a function that returns me the length of a continous
sequence of identical elements in a vector. Something like (or
similar to):
example = c(1,1,1,2,2,3,3,3,3)
result = c(3,3,3,2,2,4,4,4,4)
I am quite sure there already exists a function to do this, I just cant
figure out its name. Otherwise I would start programming my own
function.
The rle() function produces the data in a different format. Together
with rep() you can get what you want:
x <- rle(example)
rep(x$lengths, x$lengths)
