Question: is rounding necessary for proportions?

[zkamvar]

think its simpler to leave within the function - people can then also use the funciton outside of an rmd if wanted.... just my reasoning but happy to be corrected!

I see these functions as helpers for calculating a certain value. These can be used for displaying tables, but can also be used for plotting and direct comparison. In the Rmarkdown document, we display the tables through kable(), which already has its own rounding facilities.

Besides, since the function returns a tibble, the rounding is not necessary even for those who don't use kable() since tibbles only print the significant digits by default.

Also more explaining to do if have to specify in options and in kable the num digits wanted...

I messed up the explanation here. The only thing that would be done is to move the digits argument to kable(), no messing around with options.

I just found out that the digits option is different from the digits
specification in knitr kables

x <- tibble::enframe(runif(3) + 69)
knitr::kable(x, caption = "default: prints 7 digits")

default: prints 7 digits

name	value
1	69.71135
2	69.97812
3	69.25433

options(digits = 2)
knitr::kable(x, caption = "options(digits = 2)")

options(digits = 2)

name	value
1	70
2	70
3	69

options(digits = 7)
knitr::kable(x, digits = 2, caption = "options(digits = 7); kable(x, digits = 2)")

options(digits = 7); kable(x, digits = 2)

name	value
1	69.71
2	69.98
3	69.25

I am a bit indifferent, not sure what is easier for folks.
