roxygen-unknown-tag

Flag roxygen tags that roxygen2 does not understand.

roxygen2 warns on an unknown tag and drops it from the generated .Rd, so a misspelled tag (@exprot, @parma) silently loses documentation—or worse, an intended @export never reaches the NAMESPACE. Custom tags from extension roclets can be suppressed with # arity-ignore roxygen-unknown-tag.

A misspelled @export:

#' Add one
#' @exprot
add_one <- function(x) x + 1

warning: roxygen-unknown-tag
 --> example.R:2:4
  |
2 | #' @exprot
  |    ^^^^^^^ `@exprot` is not a tag roxygen2 understands
  = help: Check the spelling against the roxygen2 tag index; suppress with `# arity-ignore roxygen-unknown-tag` for extension-roclet tags.
