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
