R help - Nov 2011 - detect subset in series

Dear R Users, I am curious whether there is any simple solution o my problem.

My example 'series':
series <- c(1,1,1,0,1,0,0,1,1,0,0,0,0,1)

My 'subset' of interest:
subset <- c(0,0,0,0)

Is there any function which tells me that the subset exists in my series,
and gives me position where in series is starts. In provided example the
subset exists and covers the elements 10:13 of the 'series'.

Thanks a lot , robert

?rle
?cumsum   # may be needed to accumulate the number of postions before  
the rle$lengths criterion is first met.
