I'm sorry I haven't boiled this down to a more-minimal example yet, but ... I'm working on an S3 method (tidy.merMod, in the 'broom' package). It normally handles 'merMod' objects from the lme4 package, but I'm trying to make it handle 'merModLmerTest' objects from the lmerTest package too. The merModLmerTest class inherits (as an S4) class from the merMod class. The important difference (for my current purposes) is that summary.merMod returns an object containing a coefficient table *without* degrees or freedom or p-values, while the su...

...yzup, Yield ~ Nitrogen + Treatment + (1|Rep/Nitrogen), REML = FALSE) LSD.test(yield.lmer, trt = "Nitrogen", alpha = 0.1, console = TRUE) It gives me fits. It produces errors like: Error in as.data.frame.default(x[[i]], optional = TRUE) : cannot coerce class "structure("merModLmerTest", package = "lmerTest")" to a data.frame Do you have any suggestions for that? Thanks [[alternative HTML version deleted]]
