R help - Jul 2010 - How can i draw a graph with high and low data points

Hi, 
This is my first time so bear with me if I do anything silly. I'll learn!
I'm a relatively new user of R as well so will appreciate any help.
I have a data set in the form
Trial.Group	        MeanHeart Rate		Upper confidence level			Lower confidence
level
333subj: 0-5 M		80	              	60						120etcetc

I want to plot a graph that has Trial.Group on the x axis(names, not just an
index number), Heart rate on the y axis with the Mean and upper and lower
confidence levels. Then add a line linking the upper and lower confidence
interval together and for the Mean heart rate values to go from high to low
(descending ).
Thanks

Hi Nathaniel,

Here are a few links for (short) articles that can help you get comfortable
in doing such tasks:
http://www.statmethods.net/graphs/line.html
http://www.statmethods.net/graphs/scatterplot.html

Here is a tiny example:


x <- 1:100
y <- rnorm(100)

plot(y~x)
lines(loess(y~x)$fitted ~ x)
lines(loess(y~x)$fitted + 1.96 ~ x, col = 2, lty = 2)
lines(loess(y~x)$fitted - 1.96 ~ x, col = 2, lty = 2)
