I have a matrix containing means and CIs (lower and upper in two columns, so
three columns for every data point) for several points. I have to build a
graph of these means accompained by the CIs (as wiskers). No problems with
making the graph of means, but I don't know how to introduce CIs.
Can anybody advise?
Hi mfreidin,
The dispersion function in the plotrix package does this, and even
handles those annoying situations when the CIs are very small and throw
a "zero length arrow" error.
