 मैंने कोशिश की है  ddply ()  फ़ंक्शन इस तरह:  
  ddply (mydata,। (समय, आईडी), संक्षेप, paste0 (उत्पाद, "& amp;", उत्पाद))   
 लेकिन यह काम नहीं करता है मेरी उम्मीद के रूप में। आपके उत्तर के लिए धन्यवाद।  
   और, मेरा कहना है, कैसे एसएपी में एसएपी में एहसास करने के लिए हाना डाटाबेस? बहुत बहुत धन्यवाद!
