Hello,
I'm creating graphs like the following:
x <- seq(as.POSIXct("2012-01-01"), as.POSIXct("2013-01-01"), by = "days")
y <- (1:length(x)*10 + cumsum(rnorm(n=length(x), mean=0, sd= 100)))
plot(x,y, type = 'l', xaxt='n')
axis.POSIXct(side=1,at=seq(min(x), max(x), by="months"), format = "%b
\'%y", labels = TRUE)
For aesthetic reasons, I would only like to print the year label (%y) on
the x axis at the change points of the year. In this example, there would
be a "Jan '12" and "Jan '13" with the months in between omitting the year
label.
Any clues would be appreciated!
Peter
