Minor documentation issue: tibble shows unprintable characters in vignette

[billdenney]

On my computer, the tibble in the second code block seems to show some ASCII coloring characters:

https://mrgsolve.org/docs/articles/extra/time-after-dose.html#tad-calculated-as-runtime-argument

I think that it's happening here, but I'm not sure why it's happening:

mrgsolve/vignettes/extra/time-after-dose.Rmd

Lines 34 to 46 in 2a1ed8a

	```{r, message = FALSE, warning=FALSE}
	library(mrgsolve)
	library(dplyr)
	mod <- modlib("pk1", req = "")
	mod %>%
	ev(amt = 100, ii = 4, addl = 3, time = 2) %>%
	mrgsim(tad = TRUE, add = c(3.888,5.91)) %>%
	as_tibble() %>%
	head(n = 10)
	```

Thanks, @billdenney ; looks like some other text / code that I wanted output isn't showing up. I'll look into it; maybe some tweak needed to whatever is supporting pkgdown?

[billdenney]

When I looked at the code you have, I don't see anything that looks unusual to me. The vignette itself, globals.R, and the pkgdown settings all seem benign.

Perhaps the crayon ANSI codes getting through is due to the lack of a # prefix: r-lib/pkgdown#1965

If that's the case, the vignettes could be changed to either

• use a comment prefix for the output
• disable crayon highlighting options(crayon.enabled = FALSE)

[billdenney]

That looks like the culprit.

[kylebaron]

Yeah; I like to change comment to .; that must be it. Thanks @kyleam and @billdenney .

The special comment character was reverted to the default.
