I'm using zoo to plot multiple data series, however, I am having trouble adjusting the x-axis labeling on a multiple series plot. For example, if I create a zoo object that consists of a date series and a numerical series and then plot it, I can adjust the x axis labeling using
axis.Date(1, at=seq(as.Date("1984/01/31"), as.Date("2005/10/31"), by="2 years")) and I get my x axis labels every two years. However, if my zoo object contains multiple (i.e. 3) series and I plot my data so that I get a plot window with three sub-plots (one for each series), I cannot adjust the x axis labeling using the above line of code. That is, the following does not seem to work: # create the zoo object MySeries <- cbind(RCPTOI, RNCPTOI, NRPTOI) MyZooSeries <- zoo(MySeries, Dates) # construct a plot plot(MyZooSeries, type="l", col="red", xaxs="i", xaxt="n") axis.Date(1, at=seq(as.Date("1984/01/31"), as.Date("2005/10/31"), by="2 years")) In this case, the axis.Date command does nothing to adjust the plot. For multiple series, do the axes indices change? ______________________________________________ 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.
