How do I plot data like this: Date,Series,Value 1/5/2007,Blue,300 1/20/2007,Blue,400 1/9/2007,Red,200 1/15/2007,Red,500
Two things I'm having trouble figuring out from online help & tutorials: 1) How does R handle dates? It seems there is no built-in support for dates, but some standard add-ons provide date functionality? I can also convert my dates to number of days, however I'd like my plots to show date values on the x-axis. 2) How do plots support multiple "series" of data? Using R terms, the Series is a "factor" type. I want each series to be plotted with a different color. -- View this message in context: http://www.nabble.com/Simple-Newbie-Question-tp15619566p15619566.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.
