π Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a π emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |

π Info: Validation order correctly guards is.na
In icci (icci.R:68) and vuongtest (vuongtest.R:101-104) the length check precedes is.na() via || short-circuit, so is.na() only runs on length-1 input. This avoids the vectorized-condition error the fix targets.

π Info: nested rejects numeric 0/1 input
is.logical(nested) (vuongtest.R:101) now rejects numeric flags that if(nested) previously accepted. No in-repo caller passes numeric, but external callers relying on numeric would now error.

π¨ Severity: MEDIUM
π‘ Vulnerability: Unvalidated arguments (
nested,adjinvuongtest,conf.levelinicci) passed to exported functions could trigger raw R errors deep inside internal logic (e.g.,the condition has length > 1,missing value where TRUE/FALSE needed). This leaks internal execution contexts and stack traces.π― Impact: Potential information disclosure by leaking internal logic details and stack traces when invalid inputs evaluate in native control flow functions (like
if), bypassing top-levelstop(..., call. = FALSE)safeguards.π§ Fix: Added strict type, length, and bounds validation at the very beginning of the exported functions to fail securely with
call. = FALSE.β Verification: Run
