Is it possible to make emmeans in R?
It has a very thorough set of vignettes (see the vignette topics here ), is very flexible with a ton of options, and works out of the box with a lot of different model objects (and can be extended to others ????). I’ve started recommending emmeans all the time to students fitting models in R.

To fix the .Rmd to stifle all warnings entirely, in the initial setup chunk in the document, add “` {r setup, warning=FALSE}
Why do students often struggle to get started with emmeans?
However, I’ve found that often times students struggle a bit to get started using the package, possibly due to the sheer amount of flexibility and information in the vignettes. I’ve put together some basic examples for using emmeans, meant to be a complement to the vignettes.
Which is the best way to use emmeans?
I’ve put together some basic examples for using emmeans, meant to be a complement to the vignettes. Specifically this post will demonstrate a few of the built-in options for some standard post hoc comparisons; I will write a separate post about custom comparisons in emmeans.
How does type = ” response ” work in emmeans?
Using type = “response” will return results on the original scale. This works when the transformation is explicit in the model (e.g., log (resp)) and works similarly for link functions in generalized linear models. You’ll see the message changes in the output once I do this, indicating things were back-transformed from the model scale.
What kind of comparisons can you do with emmeans?
Built in comparisons with emmeans () The emmeans package has helper functions for commonly used post hoc comparisons (aka contrasts). For example, we can do pairwise comparisons via pairwise or revpairwise, treatment vs control comparisons via trt.vs.ctrl or trt.vs.ctrlk, and even consecutive comparisons via consec.
How does the emmeans package adjust for multiple comparisons?
The emmeans () package automatically adjusts for multiple comparisons. Since we did all pairwise comparisons the package used a Tukey adjustment. The type of adjustment can be changed.
