the precipitation values extend from 1980 to 2005, but only for october,
november and december. I would like to plot just these 3 months for the given
time period (1980 - 2005). Is there a way to get these values in the x-axis.
i.e. i need a plot with its axis reading "1980, 1981, 1982 .. 2005"
(even if the months are specified then it should be of more use). for now, i get
an axis like .. "0, 500, ... 2000" (the plot is giving the index
values).
i tried changing the freq as given below, but did not work!
ts.chn <- ts(chn.arr[1:2386,4], start=c(1980, 10), end=c(2005, 12), freq=365)
plot(ts.chn)
