R help - May 2008 - plot(summary) within quantreg package

Quantreg package allows to plot the summary of models derived by quantile
regression at different taus.

The plot shows the parameters variation by varying taus: intercept and slope
(for a linear model).

Together with these values even confidence intervals may be plotted, based
on the threshold given within the summary (e.g. alpha=0.01 equals 99% CI).

However the graphic even plots the mean of all the values as a red line
together with CI. I would like to remove such a useless information from the
graphic.

Here the main code:

model<- rq(y~x,data=dataset, tau = 0.8:10/10) # here is the model

model.summary<- summary(model)

plot(sfm) # this function plots the summary parameters together with a red
line I would like to remove



Any help appreciated…

Please provide a full example that can be pasted into R (including library,
dataset as some dummy data, and what sfm means).
