[R-sig-ME] lmer and autocorrelation structures

[Chris O'Brien]

Dear mixed-modelers,

I'm interested in modelling a dataset using generalized linear mixed models 
(specifying "family=binomial" with random effects) in which there is 
temporal autocorrelation in the response. Is there a way to do this in the 
new lme4 package?  I've used the "correlation" argument in the nlme library 
to specify a correlation structure for least-square means regression, but 
this option appears not to be implemented in the new lmer call in the lme4 
package.   Is such a thing possible (and appropriate) at this time?
thanks,
