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 canĀ“t plot upper and lower C.I. lines. Any help, Kind regards Miltinho
