>Thanks Timothy for the help. Just for background, I am attaching MInitab 15 output. I would like something equivalent in output for people to understand the power of tools like Boxplot. If convinced, the clients could take the effort to learn R with rudimentary GUI support. I did Rkward and R console combination. Used Rkward to load the data and set it active. In R console I used boxplot(formula=Time~Distance+Transporter+Tonnage, data=Transportation.Time). Resultant output (attached to this mail) is the best equivalent output. I will be able to use this output in training sessions. And yes, the formula seems broken for single variable without any grouping. Thanks for the help. Vikas Garud
