However, I would like to calculate some a priori contrasts within the Moisture factor as follows:
Transect_moisture_contrasts<-matrix(c(-1,2,-1,1,0,-1),3,2)
dimnames(Transect_moisture_contrasts)<-list(levels(env$Moisture),c("I vs. X&M","X vs. M"))
contrasts(env$Moisture)<-Transect_moisture_contrasts
> contrasts(env3l$Moisture)
I vs. X&M X vs. M
X -1 1
I 2...
