R help - Sep 2008 - plotCI -- multiple plots on same graph

I have a bunch of lines I want to plot using plotCI()

What Id like to know is, how can I connect the points with a line and how
can I print multiple lines on the same graph?

1) Look into plotmeans(), a wrapper function for plotCI....it may be more
appropriate for what you're looking for and one of the default options is
to connect the points with lines. Otherwise you'll have to do a separate
call to lines() after each plotCI() call.
2) To put multiple data sets on the same axes, you'll have to do a
plotmeans/plotCI call for each data set but before the second, third, etc
plot you should call par(new=TRUE)

cheers,

At the moment, plotCI doesn't accept a type="b" argument. I'll
see if I
can fix it. You might be able to use brkdn.plot if you can feed it the 
raw data rather than measures of central tendency and dispersion.

You might want to have a look at ggplot2, e.g.
http://had.co.nz/ggplot2/geom_errorbar.html, for an alternative way to
do this.

Thank you all for the help!  I had a friend look at it and basically what he
did was do an initial plot() of the line (which was all the mean values) and
then use ylower and yupper to plot 2 addition line() which he set lyt=3 to
so they would look like points.  I know its a dirty hack but it worked!
