[R] quantile regression estimation results

[Emili Tortosa-Ausina]

Dear list,

I'm using the quantreg package for quantile regression. Although it's 
fine, there're is some weird behavior a little bit difficult to 
understant. In some occasions, the regression results table shows 
coefficients, t-statistics, standard errors and p-values. However, in 
other occasions it shows only coefficients and confidence intervals.

Therefore, the question is... Is it possible to alter this behevior 
manually, so I can ask for either confidence intervals or other types of 
information?

Thanks very much for your help.

Kind regards,

Emili
