I'm doing some data modelling and code that worked fine yesterday is not working today: I'm inputting exactly the same thing, including calling lme4.
library(lme4)
library(lmerTest)
data.model<- glmer(DV_you~Class+(1|Speaker),data=my.dfyou.2,family='binomial')
Summary(data.model)
Getting the error message
Error in (function (classes, fdef, mtable) :
unable to find an inherited method for function ‘Summary’ for signature ‘"glmerMod"’
I've tried the good old 'turn it off and turn it back on again' trick, but the same thing's happened. Any ideas why it worked yesterday and it's not working today? Thanks.
