[R] Repeated measures

I have a data set in which I have 5000 repeated measures on 6 subjects 
over time (varying intervals, but measurements for all individuals are 
at the same times).  There are two states, a "resting" state (the 
majority of the time), and a perturbed state.  I have a continuous 
measurement at each time point for each of the individuals.  I would 
like to determine the "state" for each individual at each time point.  
It looks to me like I should be able to do this with the "hidden" 
command from the "repeated" package 
(http://popgen0146uns50.unimaas.nl/~jlindsey/rcode.html), but I have 
found it a bit confusing to get started.  The distributions in the two 
states are approximately normal with differences in centrality and 
possibly variance (but I can start by assuming similar variances).
