rollapply फ़ंक्शन का प्रयोग करते समय

चिड़ियाघर पैकेज में, हमें एक तार्किक विकल्प ' by.column = TRUE / FALSE '। यदि TRUE , फ़न अलग से प्रत्येक कॉलम पर लागू होता है।

हालांकि, apply.rolling में फ़ंक्शन का PerformanceAnalytics पैकेज मुझे ऐसा कोई विकल्प नहीं दिखाई देता है निम्न की कोशिश करते समय: 

  की आवश्यकता होती है (PerformanceAnalytics) डेटा (प्रबंधक) लागू होते हैं। रोलिंग (प्रबंधक [, 1: 10, ड्रॉप = FALSE], FUN = "mean", width = 36)

यह मुझे केवल प्रथम स्तंभ की गणना देता है कोई मुझे बता सकता है कि मैं डेटासेट में सभी कॉलमों पर यह गणना कैसे चला सकता हूं।

क्या है बस rollapply () का उपयोग करने में कुछ गलत है? apply.rolling () इस पर सिर्फ एक आवरण है। 

  रोलप्ली (प्रबंधक, फ़न = मतलब, चौड़ाई = 36, द्वारा.column = TRUE)
