👋 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 New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |

행렬 열에는 기존의 행 단위 카운트를 유지하십시오.
surveyFA() 문서는 data에 데이터 프레임을 허용하고, 검증도 데이터 프레임의 열 구조를 제한하지 않습니다. 따라서 행렬을 포함한 데이터 프레임 열이 현재 입력 계약을 통과할 수 있습니다.
고유 행이 c(NA, 1, 2)인 행렬 열에서는 기존 카운트가 0이지만 새 카운트는 2입니다. 새 코드는 해당 열을 보존하므로 기존의 응답 열 필터링 결과를 변경합니다. 행렬 열에는 기존 계산을 유지하고, 원자 벡터에서는 최적화된 계산을 사용하십시오.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

💡 What:
length(stats::na.omit(unique(x)))및length(unique(stats::na.omit(x)))를sum(!is.na(unique(x)))로 대체했습니다.🎯 Why:
stats::na.omit은 S3 generic 메서드이므로 속성 할당 및 메서드 디스패치 오버헤드가 발생합니다. 벡터화된 논리 연산을 사용하면 이러한 메모리 및 시간 오버헤드를 방지할 수 있습니다.📊 Impact: 기본 계산 작업의 오버헤드를 줄여 반복문을 약간 더 빠르게 만듭니다.
🔬 Measurement: 마이크로벤치마크 결과 확인 가능.
