Your function does not seem to function very well, could you please offer a 
self-contained, reproducible example?

When writing a function, it is indicated not to use reserved commands like 
"seq" (which is a function itself, generating a sequence of numbers).

In any case, I suspect you might want to take a look on the function "rle".
See ?rle

I hope this helps,
Adrian
