Hi Fang,
An easy way of doing this is by:
> matplot(one, pch = LETTERS[1:4], type = 'b')

Subject: Re: [R] Time series graphs, question about using zoo
Hi,
Can you tell me what is the meaning for "tail, 1" in "aggregate"?
I also want to get some similar graph, but the data is not time series
data.
Suppose here is my data one, I want a graph with x-axis is just the
index(1:9).
The graph plot all the variable A, B,C,D. So there should be 4 lines for
each graph. For the A line, at each time point, the letter A should be
on the line. And the same goes for the B line.
A B C D
> 8 4 9 8
> 7 5 4 7
> 6 8 4 4
> 3 7 6 2
> 5 1 8 5
> 6 4 7 1
> 2 8 3 4
> 1 2 4 8
> 4 3 1 9
So I add a name for each row
rownames(one) <- c(1:9)
z <- zooreg(as.matrix(one), start = 1, freq = 1) z <- aggregate(z,
as.Date, tail, 1) plot(z, plot.type = "single", type = "o",
pch = c("A", "B", "C", "D"), lty = 1:2)
I get the plot, which I think it should be right. but the problem is
that the x-axis still have month (Jan, ) on it and I didnot get
"A,B,C,D" on my graph, is there any thing wrong?
