plot question

Hello:

Im a novice user of R. I was triying develop graphs with plot.lm or 
plot(gam) but I dont obtain a desire result. I would like to create a 
plot from lm, glm and gam objects showing:

1- Fit curve
2- Raw data of predictor and response variables as points.
3- Confidence intervals (95%)

Anybody can help me?
