options for default na.strings?

[olivroy]

I almost always want na.strings = "" when writing data.

I know there is a waiver function, but I don't really understand how it works.

Thanks

Might be a good idea. The waiver function is simply a blocker that indicates internally that the equivalent of NA is used. Initially it was checking for missing(na.strings), but this caused issues with Jordan’s huge wbWorkbook splitting approach in #471 iirc. Our waiver is just a custom rlang::missing_arg.

It should be straightforward to check if some global option is set.

Implemented as of #968
