The error example: (say 'pairexp' has 23 missing values)
lmm.1<-lmer(survival~Male+FemAge+pairexp+(1|ID),REML=FALSE,na.action=na.omit)
summary(lmm.1)
lmm.2<-update(lmm.1,.~.-pairexp)
summary(lmm.2)
anova(lmm.1,lmm.2)
lmm.2: survival ~ Male + FemAge + (1 | ID)
lmm.1: survival ~ Male + FemAge + pairexp + (1 | ID)...
