👋 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. |

intersect()의 비용 설명을 정확하게 수정해 주세요.
intersect()는 데이터프레임의 행 데이터를 복사하지 않는 장점은 있지만, 열 이름 벡터를 생성하고 비교·중복 제거를 수행합니다. 따라서 “인덱스만으로” 공통 열을 찾는다는 표현보다, “데이터프레임 부분 복사를 피하고 열 이름 수준에서 교집합을 계산한다”로 기술하는 편이 정확합니다.🤖 Prompt for AI Agents

Pull request overview
OpenCode cannot approve yet because required coverage evidence did not pass.
Review outcome
1. HIGH .github/workflows/opencode-review.yml:1 - Coverage evidence did not prove required test/docstring evidence
-
Problem: The required coverage-evidence job result was
failure, so OpenCode cannot establish approval sufficiency for this head. -
Root cause: Automated approval is only valid when the same-head coverage-evidence job proves supported repository test suites passed and configured docstring gates passed or were advisory, or reports not applicable because no supported source files or package manifests exist. Missing, failed, skipped, unavailable, or unsupported-tooling test evidence is a blocker.
-
Fix: Install or configure the repository test/docstring evidence tooling when source files or package manifests exist, rerun the current-head coverage-evidence job, and approve only after it reports
successwith required evidence or explicit no-source not-applicable evidence. -
Regression test: Keep the approval branch checking
needs.coverage-evidence.result == successbefore posting APPROVE, and publish REQUEST_CHANGES when coverage-evidence blocker states such as cancelled, skipped, failed, unsupported-tooling, or below-100 evidence are present. -
Result: REQUEST_CHANGES

Reason: coverage-evidence result was

💡 What: Replaced
colnames(df[cols])withintersect(colnames(df), cols)inR/aFIPC.R.🎯 Why:
colnames(df[cols])forces R to create a subsetted copy of the dataframe which incurs O(N) memory allocation and copy overhead just to retrieve column names. By usingintersect, we achieve the exact same result through simple string set intersection, bypassing the memory overhead.📊 Impact: Expected to reduce memory footprint and improve execution speed, particularly for dataframes with large number of rows and columns.
🔬 Measurement: Verified with microbenchmark locally showing significant reduction in execution time and memory footprint (verified with
profmem). All tests pass.PR created automatically by Jules for task 5404331130269867714 started by @seonghobae
