Hi there,
 
I am attempting to assess whether there is a trend in a
observations of a population that was observed on 7 consecutive days in July
for 6 years (2000, 2001, 2002, 2004, 2006, 2008).  I have count data of
the number of observations per day for each of the seven days for each of the 6
years (total of 42 days of count data).   Is there a package in R
that can accomplish this?  I have been looking through repeated measures
regression threads, but nothing seems quite right.  
 
Also, is there a package/method that would allow me to
conduct a power analysis regarding how many more years of data would be
required to detect a trend of a certain magnitude? 
 
Thanks!
 
Jake
