Hi, I'm traing to use the GLM to find tendences on my data.
E.G.
Data.frame: MyData
Len Zone Year
12 1 2002
21 1 2003
32 1 2004
32 2 2002
32 2 2003
31 2 2004
3 3 2002
4 3 2003
3 3 2004
32 4 2002
4 4 2003
5 4 2004
I want toi fing tendences on the len, if they change over the year (the
anova say yes), but I wan't to include the zone as a Random effect So, I
have something like this:
SalGLM <- glm(MyData$Len ~ factor(MyData$year))
summary.glm(SalGLM)
But, I really don't know how to incorporate the zone as a random effect,
anybody could help please?
Thanks in advance
