I need some help about programming in S language. My problem is as follows:

I have meteorological data (about rainfall measurement
each day from 1989-2002), say like

http://www.angelfire.com/ab5/get5/data.rainfall.txt
or http://www.angelfire.com/ab5/get5/R.rainfall.txt
in a sequence of 0(denoting dry day)'s and 1(denoting
wet day)'s. I want to construct a frequency
distribution table of various lengths

(1,2,3,4,5,6,7,8,9,or more) of observed wet spells

*(number of successive 1's) and dry spells (number of
*

successive 0's) occurring in data.

How should i proceed? Is there any existing program/function/package to solve such problem (seems like the algorithm should be similar to statistical run test)?

Any suggestion, direction, references, help, replies will be highly appreciated.

Thank you for your time.
