Hello, I have a "friday" problem. I'm trying to plot the number of measures by day with this command between the 2008-07-31 and the 2009-11-13 (it works) : plot(unique(as.Date(strptime(data$date, format="%Y-%m-%d %H:%M:%S))), measuresbyday) then I would like to plot vertical lines for each month. But it doesn't work because par()$usr gives 14071.16 14579.84 -7.16 213.16 and as.numeric(as.POSIXct(unique(as.Date(strptime(data$date, format="%Y-%m-%d %H:%M:%S)))[1])) corresponding to "2008-08-01" gives 1217376000
I think the last value is ok but I don't understand why the par()$usr values are so low. Any idea ? Thanks in advance and have a nice week-end, Ptit Bleu. -- View this message in context: http://n4.nabble.com/Problem-with-date-x-axis-tp948642p948642.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.
