[R-sig-ME] spatial covariance structure in glmmTMB

[Alice Domalik]

Dear list, 

I am fitting mixed effects models using the package glmmTMB to investigate habitat use. 
My current model has the form m1<-glmmTMB(count~waterdepth + temperature + chl.conc + (1|individual), family=list(family="truncated_nbinom1", link="log"), data=mydata) 
I would like to add a spatial covariance structure based on geographic coordinates (mydata$x and mydata$y). 
However, I do not know how to modify my model formula to include a spatial covariance structure. Does anyone have example code to show how this is done? 

Any help would be much appreciated!
