Bug

%$% not working ANOVA Post-hoc testing I substituted with and it worked.

https://openintro.shinyapps.io/ims-05-infer-08/#section-post-hoc-testing

also first tidy in the solution needs pipe or variable instead of _____

Not positive but I think the comments on the first should be with adjustment and the third should be Compare with adjusted pairwise t-tests

Reproducible Example

# Run a pairwise t-test on wordsum and class, without adjustment
t_test_results <- gss %$%  
  pairwise.t.test(x = wordsum, g = class, p.adjust.method = "bonferroni")

## Alternative method 
t_test_results <- pairwise.t.test(gss$wordsum, gss$class, p.adjust.method = "bonferroni")

# Tidy the result
tidy(___)

## Compare with un-adjusted pairwise t-tests
gss %$% 
  pairwise.t.test(wordsum, class, p.adjust.method = "none") %>% 
  tidy()

Expected Behavior

# Run a pairwise t-test on wordsum and class, with adjustment
with(gss, pairwise.t.test(x = wordsum, g = class, p.adjust.method = "bonferroni")) %>%
  tidy()

## Alternative method 
pairwise.t.test(gss$wordsum, gss$class, p.adjust.method = "bonferroni") %>%
tidy()

## Compare with adjusted pairwise t-tests
with(gss, pairwise.t.test(wordsum, class, p.adjust.method = "none")) %>%
  tidy()

Thanks for bringing this to our attention! You are correct that the first comment should be "with".

The error with the %$% pipe was caused by not loading the magrittr package in the tutorial setup. This has been corrected and the error should go away upon our next deployment.

I will keep this issue open until we deploy and the error is gone.

Confirmed, the latest deployment fixes this issue.
