[R] Repeated measures regression

[knussear]

Hi List,

Just wondering if there is such a thing as repeated measures 
regression, and if so, can R do it?

I have repeated measurements of 10 individuals over a 45 day period, 
and I would like to regress their daily activity time against a daily 
environmental temperature. If I do so using averages of activity time I 
find a significant negative correlation, but I worry that because I 
have used the same 10 individuals for each daily mean that the daily 
averages are not independent.

Can anyone help?

Thanks
