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?
