Hello,
Try the following.
(rr=ts(rr,start=c(2012,5),frequency=12))
plot(rr, xlab="2012 - 2013", ylab="event freq", xaxt = "n", col="blue")
labs <- format(as.Date(time(rr)), "%b-%Y")
axis(1, time(rr), labs, cex.axis = .9, tcl = -.5, las = 2)
Hope this helps,
Rui Barradas

Hi,
I'm trying to plot a simple time series. I'm running into an issue with
x-axis
The codes below will produce a plot with correct x-axis showing from Jan to
Dec
rr=c(3,2,4,5,4,5,3,3,6,2,4,2)
(rr=ts(rr,start=c(2012,1),frequency=12))
win.graph(width=6.5, height=2.5,pointsize=8)
plot(rr, xlab="2012", ylab="event freq", xaxt = "n", col="blue")
axis(1, time(rr), rep(substr(month.abb, 1, 3), length = length(rr)),
cex.axis = .9, tcl = -.5, las = 2)
However, if I change the start point from Jan 2012 to May 2012, which is
(rr=ts(rr,start=c(2012,5),frequency=12))
Then run the codes below
plot(rr, xlab="2012 - 2013", ylab="event freq", xaxt = "n", col="blue")
axis(1, time(rr), rep(substr(month.abb, 1, 3), length = length(rr)),
cex.axis = .9, tcl = -.5, las = 2)
In the the new plot produced, x-axis is still showing from Jan to Dec, not
from May to April as I desired.
How to fix x-axis? Is it possible to fix it WITHOUT modifying the object
"rr"? Also, ideally, I would like to have each time point on x-axis showing
month/year, not just month. How to do that?
Any help and input will be much appreciated!
Thanks
Jerry
