`display()` and paired t-test output

[profandyfield]

display() doesn't like the traditional entry paired t.test ... I assume because of the $ in the variables.

sleep2 <- reshape(sleep, direction = "wide",
                  idvar = "ID", timevar = "group")

## Traditional interface
t.test(sleep2$extra.1, sleep2$extra.2, paired = TRUE) |> 
  model_parameters() |> 
  display()

## Formula interface
t.test(Pair(extra.1, extra.2) ~ 1, data = sleep2) |> 
  model_parameters() |> 
  display()

Formula interface is displayed fine in rendered document, but the traditional interface is not (columns are thrown off as is the parameter label).

What do you mean by "doesn't like"?

[profandyfield]

Formats the output weirdly - see example in original comment.

[strengejacke]

Ah, I see, the $ needs to be escaped

[bwiernik]

It's not formatting it like a paired test (it has the Group) column

Can you please provide a fully working reproducible example? For me, the output is:

sleep2 <- reshape(sleep, direction = "wide",

## Traditional interface
t.test(sleep2$extra.1, sleep2$extra.2, paired = TRUE) |>

  display()

Parameter	Group	Difference	t(9)	p	95% CI
sleep2$`extra.1	sleep2`$extra.2	-1.58	-4.06	0.003	(-2.46, -0.70)

Paired t-test

Alternative hypothesis: true mean difference is not equal to 0

In which context are you producing that table?
