This will not work if A and B are data frames, BTW. -Deepayan __________________________________________________ -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)

Hi all,
Assume i have two dataframes A and B with characters objects
for example,
A<-rbind(c("the","is"),c("and","!"))
B<-rbind(c("car","red"),c("blue","!"))
and i would like to obtain the C dataframe
C<-rbind(c("the car", "is red"),c("and
blue","!!"))
What is the solution without loops ?
Thanks
Olivier
