That is, medley2 = aov(diversity ~ zinc, data=medley.clementis) emmeans::emmeans(medley2, "zinc") You can see the difference in the calls: medley2$call medley.clementis.aov$call This works for the other data set as well, e.g. keough2 = aov(serpulid.ln ~ biofilm, data=keough.raimondi.ln) ~ Sal Mangiafico On 1/8/2018 4:44 PM, Rolf Turner wrote: On 07/01...

I am a Professor of Statistics at Indira Gandhi Krishi Vishwavidyalaya, Raipur, India. While teaching in class about analysis of variance using R, I was doing a one-way analysis for the two data-sets given below in the R-class. I got a typical error in "emmeans" package, please help: Data-set-1: -------------- Medley and Clements (1998) investigated the impact of zinc contamination (and other heavy metals) on the diversity of diatom species in the USA Rocky Mountains.

...ad their own dataset, select columns they want an ANOVA analysis run on, and generate graphs that will allow users to view their results. However, I am getting the following error: *"Argument is of length zero."* Being new to Shiny, I am having trouble passing the user input column to an emmeans argument in order to do a post hoc analysis, and using that information to produce a graph. Can somebody help me with this? *The code for my dataset and application are provided below; copying and pasting directly into R should generate the reproducible example.* In my application, the following c...

Dear R-Devel, I seem to no longer be able to access the bug-reporting system, so am doing this by e-mail. My report concerns models where variables are explicitly referenced (or is it "dereferenced"?), such as: cars.lm <- lm(mtcars[[1]] ~ factor(mtcars$cyl) + mtcars[["disp"]]) I have found that it is not possible to predict such models with new data. For example:

I read through the editorial. This is the one of the most mega-ultra-super-biased articles I've ever read. e.g. The authors encourage Baysian methods, and literally encourage subjective approaches. However, there's only one reference to robust methods and one reference to nonparametric methods, both of which are labelled as purely exploratory methods, which I regard as extremely

Which confint() method do you have in mind? There is at least four of them by default in R, and many additional classes could make use of stats:::confint.default by implementing vcov(). >
