Thank you! That gets the data in exactly the shape I was expecting. I was hoping to get the graph showing all lines on one plot, but coloured according to plant. I tried to change screen=DF$plant for groups=DF$plant, but it doesn't work, and I can't figure out from the documentation why it doesn't work (I think I need to more thoroughly understand data types first). Could you point me in the right direction? Thanks so much for your help so far. -- View this message in context: http://r.789695.n4.nabble.com/How-to-import-time-series-data-tp4381372p4383740.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.
