[R] Plot Date

[Gabor Grothendieck]

Try this.  We first generate some test data, then we plot the
data without the x axis.  We generate a subset of the times
consisting of a sequence of every 7 months and create an
axis with that.  Then we add smaller ticks every month.


library(zoo)

# test data
x <- seq(0, 10*365)
z <- zoo(x, as.Date("1990-01-01") + x)

plot(z, xaxt = "n")

tt <- seq(as.Date("1990-05-20"), time(z)[length(z)], by = "7 months")
axis(1, tt, format(tt, "%d/%m/%y"), cex.axis = 0.7, tcl = -0.6)

tt <- seq(as.Date("1990-01-20"), time(z)[length(z)], by = "months")
axis(1, tt, FALSE, tcl = -0.3)
