First get the correct representation which here would be a multivariate zoo series with 51 time points and 6 components series and then plot it using zoo's plot function:
z <- zoo(matrix(dat, 51), time(dat2)) # all in one panel plot(z, pch = letters[1:6], screen = 1, type = "b", col = 1:6) # or in separate panels (same but omit screen = 1) plot(z, pch = letters[1:6], type = "b", col = 1:6) There are many examples of plotting zoo series in the 3 vignettes that come with zoo and also in ?plot.zoo and ?xyplot.zoo If you wish to use ggplot2 you can extract the data and times into a new data frame and use that data frame for further computation. DF <- cbind(tt = time(z), as.data.frame(z)) On Fri, Sep 25, 2009 at 9:32 AM, Bogaso <bogaso.christo...@gmail.com> wrote: > > Thanks for this reply.
