[R] error bars on xy plots and barplots and histograms
Dear all I have yet to find code for making and showing error bars. Is there some idea that the simple presentation of confidence intervals is not " good statistics"? Any leads appreciated.

Chris, computation of confidence intervals is left to the user. Showing them can be achieved using the arrows() function. I hope that this helps, Andrew On Thu, Oct 06, 2005 at 08:19:27AM -0600, Chris Buddenhagen wrote:> Dear all > > I have yet to find code for making and showing error bars.
