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?

Have you considered "predict.lm"? The documentation includes an example that will produce predicted lines plus both confidence and tolerance intervals. Follow that with "points(x, y)" to add the data points. hope this helps. spencer graves

Here is a link to a post of mine back in March which provides example code for plot.lm(): https://www.stat.math.ethz.ch/pipermail/r-help/2003-March/030057.html HTH, Marc Schwartz
