Welcome to R.
You can start by looking at the predict function for the regression model you are using (e.g., ?predict.lm if you are using a linear model).
Then do something like so:
data(cars)
cars.lm <- lm(dist ~ speed, cars)
dist.pred <- predict(cars.lm)
plot(cars$speed, cars$dist, ylim = c(-2, 120))
lines(cars$speed, dist.pred, col = "red", lwd = 2)
HTH, Andy
