Hi Yung-jin,

❝ I like to thank you for this post first


Welcome.

❝ (very nice codes).


I would never (!) use such a code given the nice vectorization possible in R. It was only intended as an example to get the means without a model.

❝ But do you think that we should also present df, upper/lower CI (90% or 95%), and p values stuffs for lsmean?


IMHO, the df makes sense since it tells us whether we pulled the right stuff from the model.
The CI is nice to know but not necessary. If the CIs overlap there is no significant difference between treatments. So what? No agency asks for it.
I never understood the purpose of the t- and p-values. What is tested here? A difference to zero or what?

❝ Or just keep it simple as you suggest?


Please don’t think about using this awful code!
