टिप्पणियां धीमी गति से आर करें?

Question

टिप्पणियां R धीमा करें?

यह सवाल अजगर के बारे में StackOverflow पर दो बार कहा गया है:

Do comments slow down an interpreted language? Will excessive commenting of code slow execution?

python के लिए इस सवाल का जवाब 'नहीं' प्रतीत होता है। मुझे दो भाषाओं के बीच मतभेदों के बारे में पर्याप्त जानकारी नहीं है यह जानने के लिए कि R के लिए ये उत्तर कितने प्रासंगिक हैं।

R में सफेद स्थान के बारे में एक समान प्रश्न है। फिर जवाब 'नो' प्रतीत होता है।

does white space slow down processing

Answer 1

आर के लिए इस सवाल का जवाब जब तक कि मैं कहीं नीचे एक गलती की होने के लिए 'हां', प्रकट होता है।
