R help - Jul 2011 - Plot fn, xlim when x is a date. XXXX

Hello everyone,

I have the following x variable:

DATE<-as.Date(as.character(data12$DATE),"%m/%d/%Y")

This works fine, however, I want to plot multiple years of data on separate
plots by month. All years have all 12 months data except 2011; HOWEVER I
need the x axis limits to remain the same. I tried using xlim=c(1,12) and
that did not work.

Can someone please advise?

Thank you!

Dan

You need to use dates as xlim values.  They will vary from year to year 
(January 2010 is a different date than January 2011), but it's 
reasonably easy to compute the limits you want when you subset the 
dates.  For example

x <- as.Date(paste("1/",1:6,"/11", sep=""),
"%d/%m/%y")
jan <- x[1]
dec <- as.Date("1/12/11", "%d/%m/%y")
plot(x, 1:6, xlim=c(jan, dec))
