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
