thank you for your reply.. As i have told you earlier... i want to plot the total no.of birds counted for each day and plot total no.of birds for each day.. one level for each day ..
i wanted to normalize the data.. since i don't have the data for equal no.of hours for all days.. for example on 2011-04-23 i have a data for 2 hours.. but on 2011-05-03 i have data for 8 hours.. that is why i am dividing the data by the no.of hours of data on that particular day.. so... i will create a dataset with dates from the whole month using the above command you have mentioned.. .. and plot my data for these values.. since my data has some dates missing.. i won't get any bars on those particular days.... how can i place a * on those missing days.. thank you -- View this message in context: http://r.789695.n4.nabble.com/plotting-date-data-over-couple-of-months-tp3666298p3668433.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.
