[R] how to print the full name of the factors in summary?

[Adaikalavan Ramasamy]

It would be useful to say which package the object SJ comes from or 
provide a more reproducible example.

Assuming that Demand variable is continuous and you are fitting a 
standard lm() model, then your results looks suspicious. Where are the 
coefficients for Month, Holiday, Season?
