Plotting dates
I'm trying to plot observations against observation dates and getting julian
dates along the x-axis:
library(date)
Week<-as.date(c("05/02/03","05/09/03","05/16/03","05/23/03","05/30/03","06/0
7/03","06/14/03"))
Leafminers<-c(0,2,5,10,4,6,5)
Diglyphus<-c(0,0,4,5,7,3,1)
LeafDig<-cbind(Week,Leafminers,Diglyphus)
plot(LeafDig,ylim=c(0,20),main="Leafminers",ylab="Observed
numbers",xlab="",adj=0,bty="l")
points(Diglyphus,pch=2)
lines(Diglyphus,lty=2)

Comparing GLMMs and GLMs with quasi-binomial errors?
Dear All,
I am analysing a dataset on levels of herbivory in seedlings in an
experimental setup in a rainforest.
I have seven classes/categories of seedling damage/herbivory that I want to
analyse, modelling each separately.
There are twenty maternal trees, with eight groups of seedlings around each.
Each tree has a TreeID, which I use as the random effect (blocking factor).
There are two
