Plotting a time series
don't use the type argument. You are telling plot to plot points. also please use dput() to make example code that can be cut and pasted out of the email right into R, so that your problem is reproducible. Stephen

when I use plot(data) the plot looks fine except that the plot symbols are
broken horizontal lines. How do I change the plot symbol? I have tried:
plot(data, type="p")
and I get the same result.
Thanks,
Tom
