Thanks for reply.
The following code is working but only patially. How to get the condensed
values separated by comma.
dataframe1 = data.frame(cbind(Src = c(1,1,1,2,3), Target1 =
c('aaa','bbb','ccc','aaa','ddd')));
dataframe2 = data.frame(cbind(Src = c(2,3,4,4,4), Target2 =
c('aaaa','dddd','bbbb','eeee','ffff')));
dataframe3 = data.frame(cbind(Src = c(1,3,5,6,6), Target3 =
c('xx','yy','zz','tt','uu')));
merge(dataframe3, merge(dataframe1,dataframe2, by = 'Src', all=TRUE), by =
'Src', all=TRUE)
1> merge(dataframe3, merge(dataframe1,dataframe2, by = 'Src', all=TRUE), by
= 'Src', all=TRUE)
Src Target3 Target1 Target2
1 1 xx aaa <NA>
2 1 xx bbb <NA>
3 1 xx ccc <NA>
4 3 yy ddd dddd
5 5 zz <NA> <NA>
6 6 tt <NA> <NA>
7 6 uu <NA> <NA>
8 2 <NA> aaa aaaa
9 4 <NA> <NA> bbbb
10 4 <NA> <NA> eeee
11 4 <NA> <NA> ffff
Thanks
