thanks to your guys help I am closer to solving my problem but I have some small problem. So let's say I start with
>data number day hour 1 17 10 2 17 11 3 17 6 4 18 4 5 18 10 6 19 8 7 19 8 I want to split to odd days, which I am able to do, I call this object frames, which looks like: > frames $`1` c1 day1 hour1 1 1 17 10 2 2 17 11 3 3 17 6 $`2` c1 day1 hour1 4 6 19 8 5 7 19 8 Now I want to make plot of the hours of both days, but not by hand. I need some sort of loop for this. How is this done? So par(mfrow=c(1,2)) for(…) plot(…hours…) thanks for the help -- View this message in context: http://r.789695.n4.nabble.com/plotting-from-dataframes-tp4655851.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.
