any-is-na

Flag any(is.na(x)), which is the purpose-built anyNA(x) — faster (it short-circuits and builds no intermediate logical vector) and clearer.

The rule fires only on the clean single-argument shape and only when both any and is.na resolve to base R; a local redefinition of either is left alone.

Testing for any missing value:

if (any(is.na(x))) stop()

1 | if (any(is.na(x))) stop()
  |     ^^^^^^^^^^^^^ `any(is.na(x))` is the faster, clearer `anyNA(x)`
  = help: Use `anyNA(x)`.

After applying the fix:

if (anyNA(x)) stop()
