R help - Sep 2006 - Plot Confidence Interval for Regression

Dear R-friends
   
  I fitted a regression using GLM and plotted fitted values agaist X axis.
  Now I need plot upper and lower confidence intervals (95%) for this fit.
  Acoording to ?lm help and can use something like :
     [ predict.lm(mod, se.fit=T, interval = "confidence", level=.95) ]
  to estimate confidence intervals. In fact this command run fine, but I can´t
plot upper and lower C.I. lines.
   
  Any help,
   
  Kind regards
  Miltinho
