Since the recent update to package lme4, I now get an error when trying to
print the results using lmer to obtain model estimates for anything other
than a liner mixed model. For example,
(fm1 <- lmer(decrease ~ treatment + (1|rowpos) +
(1|colpos),family=poisson(),
data=OrchardSprays))
Produces the error:
Error in checkSlotAssignment(object, name, value) :
Assignment of an object of class "NULL" is not valid for slot
"frame" in an object of class "summary.lmer"; is(value, "data.frame") is not
TRUE
Error in show(new("summary.lmer", object, useScale = TRUE, showCorrelation =
FALSE)) :
Unable to find the argument "object" in selecting a method for
function "show"
My version information:

arch i386
