[R] output

[Adaikalavan Ramasamy]

Season X is taken as the reference category. So the output 
"factor(season)y   10.59739" means the feed_intake is higher by 10.59 
units in Season Y _compared to_ Season X.

Change your levels in season. E.g.
   season <- factor(season, levels=c("Z", "X", "Y")
which means that Z will be taken as the reference category. Also read 
help(contrasts).

Regards, Adai
