[R] Problems plotting time-series with multiple lines

[Felipe Csaszar]

He you checked this example?:
z <- ts(matrix(rt(200 * 8, df = 3), 200, 8), start = c(1961,1), frequency = 
12)
z <- window(z[, 1:3], end = c(1969, 12))
plot(z, plot.type = "single", lty = 1:3, col = 4:2)

It is from the help page of plot.ts

Dear Sirs,

I want to plot a time series with lines, one for each variable.
I have a dataset with dates, and the values.
How can i plot?
I could plot one variable using index plot, bu i want to put the labels on X
axis. But i had two problems:
1) The plot function, when i try to plot(x,y), incorectly sort the date (on
X axis). My dataset has the date in string format "%d/%m/%Y).
If i try to converto to date using
as.Date(Dataset.dates,"%d/%m/%Y)
it interprets the %Y incorrectly.

2) I have 187 rows. So i have to plot only some of the dates, not all.

Please, help me.

Thanks in advance.

Best Regards,

José Augusto M. de Andrade Jr.
