💡 What: surveyFA.RsurveyFA() 함수 내에서 최소 p-value를 가진 항목(bad item)을 찾을 때 사용되던 sort(p_values, decreasing = FALSE)[1L] 구문을 which.min(p_values)로 교체했습니다.
🎯 Why: 기존 방식은 단순히 최소값 하나를 찾기 위해 배열 전체를 정렬하므로 O(N log N)의 시간 복잡도를 가집니다. which.min()을 사용하면 O(N) 선형 탐색으로 동일한 결과를 얻을 수 있어 성능 병목을 해결할 수 있습니다.
📊 Impact: 아이템 수가 많을 때 배열 정렬 오버헤드를 완전히 제거하여 불필요한 실행 시간을 단축시킵니다.
🔬 Measurement: 기존 테스트(testthat)를 동일하게 실행하여 기능 변경 없이 통과함을 확인했습니다.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request.

When you start a review, I'll add a 👀 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 @jules. You can find this option in the Pull Request section of your global Jules UI settings. You can always switch back!

New to Jules? Learn more at jules.google/docs.


For security, I will only act on instructions from the user who triggered this task.

Warning

Review limit reached

@seonghobae, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 5 minutes

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Closing as superseded by #178. #178 contains the same O(N) which.min() production behavior behind a bounded helper and proves prior sort equivalence for ties/NA/empty vectors plus the real minimum-variance removal path. This branch’s journal formatting and markdownlint file do not add a unique product contract.
