Hi R users, I am new to R and am trying to merge data frames in the following way. Suppose I have n data frames each with two fields. Field 1 is common among data frames but may have different entries. Field 2 is different.
Data frame 1: Src Target1 1 aaa 1 bbb 1 ccc 2 aaa 3 ddd Data frame 2: Src Target2 2 aaaa 3 dddd 4 bbbb 4 eeee 4 ffff Data frame 3: Src Target3 1 xx 3 yy 5 zz 6 tt 6 uu And so on... I want to convert this into a data frame something similar to: Src Target1 target2 target3 1 aaa,bbb,ccc - xx 2 aaa aaaa - 3 ddd dddd yy 4 - bbbb,eeee,ffff - 5 - - zz 6 - - tt,uu Basically I am trying to make a consolidated table. Help appreciated.
