Dear d_labes,

❝ What you describe must be an effect of using an add-on package with comes with the possibility to consider multiplicity in calculation of confidence intervals.

Thanks a lot for commenting

Can you try this:

library("lsmeans")
set.seed(12341)
v1=c(rep("A",10),rep( "B",10), rep( "C", 10))
v2=c(rep("Q",10),rep( "W",10), rep( "E",10))
Foo=sample(v1)
Bar=sample(v2)
y=runif(30)
M=lm(y~factor(Foo)+factor(Bar))

confint(pairs(lsmeans(M, "Foo")), adjust="none")
confint(pairs(lsmeans(M, "Foo")), adjust="bonferroni")
confint(pairs(lsmeans(M, "Foo")), adjust="eat.my.shorts")
confint(pairs(lsmeans(M, "Foo")))
# HAPPY NEW YEAR


It gives four different results here. You can see adjust is passed as an argument to the confint function so can't see how it would be part of lsmeans or pairs args.
