Hi, I've an issue adding an interaction to a GAMM: My model was of form: gamm1 <- gamm(TOTSR ~ fROT + s(PH) + s(LOI) + s(ASP) + s(SQRT_ELEV) + CANCOV + s(SQRT_TOTCWD) + s(WELLF) + s(WELLN) + s(OLDWDLD) + s(DISTWOOD) + s(Annprec) + s(OLDWDLD:DISTWOOD) + (1|fSITE), family = poisson, data = BIOFOR2) with interaction of s(OLDWDLD:DISTWOOD). However I got this error message below but don't know what it means? (my data is composed of info for 150 plots) #I Warning messages: #2: In OLDWDLD:DISTWOOD : # numerical expression has 150 elements: only the fir...

...m looking for activity differences between three features (4 sites per feature). I am also looking for peaks of activity across time (Day). I am using a gamm since I believe these are nonlinear trends with nested data. gammdata<-gamm(lcin~Temp+s(Day)+fType+wind+fFeature+Forest+Water+Built, list=fSite,data=data, family=gaussian) summary(gammdata$gam) summary(gammdata$lme) anova(gammdata$gam) I can see which variables are significant but I was wondering if there was a way to do a post hoc to see differences between features? Or is there a way to compare different models (feature) for significa...

My GAMM model is to find drivers of species richness in forests is gamm1<- gamm(Total Species Richness ~ fROT + s(PH) + s(LOI) + ASP + s(SQRT_ELEV) + CANCOV + s(SQRT_TOTCWD) + s(WELLF) + s(WELLN) + s(OLDWDLD) + s(DISTWOOD) + s(Annprec), random=list (fSITE =~1), family = poisson, data = BIOFOR3) My issues are that the validation graphs are using methods I'm unfamiliar with e.g. square rooting values and Pearson's residuals. I'm following as best I can recommendations in Wood 2006 and Zuur 2009 but have some (I think) basic questions on g...
