HI,
It is better to show a reproducible example using ?dput().? May be this helps:
#vector
vec1 <- seq(as.Date("2002-01-01"),
as.Date("2009-12-31"),by="1 day")
#Assuming that length of the vector is the same as ?nrow of matrix.
set.seed(532)
mat1 <- matrix(cumsum(rnorm(length(vec1)*5)),ncol=5,
dimnames=list(NULL,LETTERS[1:5]))
library(xts)
library(xtsExtra)
plot(as.xts(mat1,order.by=vec1),major.format="%Y",screens=1,
main="Time series plot", auto.legend=TRUE,auto.grid=FALSE,col=5:1)
You should also check ?legend()
A.K.
thank you so much. it tried the 2nd way and it is working perfectly. could you
also tell me how I can select a vector which is then used for the x axis?
let's say I want some Dates 2002 to 2009, currently I have a vector called
date which contains of every single day from 2002 to 2009, is there a way to get
this on the x axis (just the year)? in Addition, is there some command to add a
legend, titles, Change Color etc? From what I find on the Internet, I just
don't understand how that is working. thanks again for the help!

Hi everyone, I have started using R and although I am used to some other
languages, I am struggling doing a plot that contains several lines which each
correspond to a column of the Matrix which all my data. I tried to google it but
unfortunately, it haven't found anything which helped me and also the
description didn't really give me a hint what to do. Let's say I have
Matrix calles Data_Set which consists of 6 columns and let's say 100 rows.
in the first column, I have the date, which is also the x-axis of my plot. The
next five column contain the time series, for each of them I want I line drawn
in the plot. I have installed the lattice package and I tried several things
using the xyplot command, but it didn't work. thanks so much for your help.
