Global Option for NA symbol and locale

[retodomax]

Package gt has a few global options (see ?`gt-options`). For Example, the function gt() checks by default for a global option in the argument row_group.sep i.e.

gt(
  row_group.sep = getOption("gt.row_group.sep", " - ")
)

I think a similar approach would make sense for other arguments which a user usually wants to set globally (e.g. locale and NA value)

gt(
  locale = getOption("gt.locale", "NULL")
)
sub_missing(
  missing_text = getOption("gt.missing.text", "---")
)

For the NA symbol, it would be even better if the sub_missing() function would not have to be explicitly called.

A similar option also exists for the kable() function

options(knitr.kable.NA = '')

Or maybe there is there another way to achieve this without having to set the locale and NA value for each table individually?

Some global options do exist but I'm generally not in favor of global options because they reduce reproducibility. Because of that, I think these options cannot be made global.
