[R-sig-ME] gamm4 model fit error

[Nicholas Lange]

Hello,

I'm running R.3.1.1 on Mac OS X 10.6.8 with gamm4 version 0.2-2 and lme4 version 1.1-7. I get the following error when trying to fit the simplest gamm4 model I can think of:

> fit = gamm4( y ~ s(x))

Warning message:
In deviance.merMod(ret$mer) :
 deviance() is deprecated for REML fits; use REMLcrit for the REML criterion or deviance(.,REML=FALSE) for deviance calculated at the REML fit.

> fit

$mer
Linear mixed model fit by REML ['lmerMod']
REML criterion at convergence: 3891.265

$gam

Family: gaussian 
Link function: identity 

Formula:
TotalBrain ~ s(AgeYears)

Estimated degrees of freedom:
5.28  total = 6.28 

lmer.REML score: 3891.265     

Not the usual regression summary table, no p-values.

Does anyone see what's wrong? Any help would be greatly appreciated.
