Hi, I am with a problem on how to do a comparison of values. My script is as follows:
repeat{ cat("How many teams to use? (to end write 0) ") nro<-scan(n=1) if(nro==0)break cat("write the", nro, "teams names \n") teams<-readLines(n=nro) if (teams[1]==teams[2)next else print(teams) } On this example I only compare teams 1 name with teams 2 name, and if they are the same the scrip starts again. If I had 10 teams how could I make it compare the "nro" number of teams names in order to check if the same name has been written more then once? The idea is, if the same name is written more then once it should give an error and start the scrip again by asking the teams names again. Two more things: With the next function the script stats from top, I mean starts by asking the number of teams to use. Can I make it that it goes directly to asking teams names? And when it checks anc find out that a certain name has been written twice can it produce a message warning that this error happened before asking the teams names again? Many thanks Regards, A.Dias. -- View this message in context: http://r.789695.n4.nabble.com/Help-with-IF-operator-tp3178129p3178129.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
