Detect the first present argument name in dots.

dot-detect_first_present.Rd

Detect the first present argument name in dots.

Usage

.detect_first_present(dots, candidates = c("q", "x"))

Details

Some wrapped scalar functions accept either q or x as their first numeric argument depending on the original API. This helper inspects ... and returns the first candidate name that is actually present so wrapper code can map user input onto the target function signature.
