💡 What: length(unique(stats::na.omit())) 대신 더 빠르고 벡터화된 논리 연산인 sum(!is.na(unique()))를 사용하여 고유한 비결측값(non-NA)의 개수를 구하도록 변경했습니다.
🎯 Why: 기존 코드는 내부적으로 S3 메서드 디스패치를 유발하고 속성 할당 복사로 인해 오버헤드를 발생시킵니다. 이를 단순화된 벡터 논리 연산으로 대체하여 성능 향상을 이룹니다.
📊 Impact: 불필요한 메서드 디스패치 및 오버헤드가 줄어들며, 큰 데이터셋이 주어질 수록 연산 속도가 더욱 빠르게 향상될 것입니다.
🔬 Measurement: 기존 testthat 테스트 통과 완료, 100% 코드 커버리지 유지를 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!
The optimization can retain constant items when columns define custom missing values, potentially changing fitted results. Restore the original filtering semantics and add a focused regression test; the established impact is limited to specialized inputs.

I couldn’t find a match for that exact search query. It appears to target the `as.matrix.data.frame` implementation in R’s `dataframe.R`, but the search results don’t establish whether the function contains the specific `is.numeric`, `unlist`, and `X` terms.

결측값을 제거한 뒤 고유값을 세어 주세요.
is.na()가 999를 결측값으로 처리하지만 unique()가 클래스를 제거하는 숫자 열에서는 상수 문항이 유지됩니다. 이 문항은 mirt에서 두 범주로 처리되어 모델 결과를 왜곡할 수 있습니다. 기존 순서를 복원해 주세요.
