I am continually amazed at how many ways there are to skin a cat in R!

In the following cs increases by 1 for each nonzero
entry in x. Thus the zeros plus the preceding nonzero
form runs in cs. seq(cs)-match(cs,cs) assigns 0
to the first element of each such run, 1 to the next,
2 to the next and so on. Thus shifting it forward and
adding 1 gives the number of prece

You are absolutely correct Marc; thank you for making this assumption!
While it will take some time for me to rightfully understand the logical
ordering of your proposed function, it certainly seems to produce the result
I was looking for, and economically at that. rle is indeed highly useful
