Many thanks,

Ah, yes, the need to "condense" escaped me. I thought you wanted to
write out the final result separated by commas.
You will need to do the "condensing" separately. Unless someone else
has a more elegant idea, I guess something along the lines of
df2srcs<-unique(dataframe2$Src);
df2new<-data.fram
How??
I dont think there is any parameter that does this job.
I came up with ddply function in plyr package but having tens of dataframe
and doing it in a for loop may not be a good idea.
ddply(test, ~ Src , colwise(paste, .(Target1)), collapse ="," );
Can you please write how it can be done by
?write.csv
Cheers,
David.

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('','','',
Hi, try
?merge
Best,
David.

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
1aaa
1bbb
1ccc
2
