[R] How can i draw a graph with high and low data points

[Greg Snow]

There are several functions in several packages for plotting intervals that will give you plots much better than the excel one.  The RSiteSearch function or the sos package may help you find those. 

But it is also easy to create such plots using just a few lines of R code and base graphics.  Read the help pages for plot.default (look at the ylim argument) and the segments function (the order and seq functions may also be of use).
