How to make comparism between lines and check about biometryassist

[rogerssam]

Good day all,

I know when working with the emmeans package I can make comparism between many lines and check variety. that is the aim is to select all lines that out perform the check. But I don't know how to achieve this using your pacakge. Thank you very much for writing this package. Merry Christmas and Happy New Year in Advance.

Here is an example of what I want to achieve:

Load Packages

library(tidyverse)
library(agridat) # To get the omer.sorghum dataset
library(lmerTest)
library(emmeans)
library(biometryassist)

Model

model <- lmer(yield ~ gen + env+(1 | rep), data = omer.sorghum)

summary(model)
test <- anova(model, ddf = "Kenward-Roger", type = 3)
test

Post Hoc Test

comparisons.G18 <- emmeans(model, specs = trt.vs.ctrl ~ gen, ref = 18)
#str(comparisons.G18)
#names(comparisons.G18)

comparisons.G18

comparisons.G18$contrasts # Get the contrast

comparisons.G18$contrasts %>%
as_tibble() %>%
arrange(desc(estimate))

This does not work

multiple_comparisons(model.obj = model,classify = 'gen',specs = trt.vs.ctrl ~ gen, ref = 18)

Hi @BB1464, this isn't currently implemented, but I will add it as a feature request and see what I can do to make it happen.

Thanks @rogerssam, I will be looking forward to it.
