這是使用R解析這樣的日誌文件的最佳方式嗎?如何使用R解析網絡服務器日誌?

我必須考慮邊界情況,如在一行(內部和外部)中有2個IP。
謝謝!
正則表達式也許可以用來解析這一點,類似於您在Perl做什麼。我的問題是,你最終希望數據看起來如何? –
準備編寫bitchy正則表達式。標記的表達式和'gsub'是你的朋友。 – aL3xa
如果你想讓你的生活更輕鬆Apache有一個非常靈活的方式來指定日誌文件的樣子。這種「通用日誌」格式是一種痛苦,因爲一半的東西是空間分隔的,另一半用方括號分隔,另一半用引號括起來,另一半用逗號分隔......它只是不加向上。請參閱http://httpd.apache.org/docs/1.3/logs.html以瞭解如何重新配置日誌並使其健康(假定訪問Web服務器)。 – Spacedman
