Dear list members,

When I create a simple scatterplot with a regression line (se below) the line is automatically extrapolated outside the range of data points. Why is this and how can I prevent R from extrapolating the regression line?

Thank you in advance,
Johan

model<-lm(Herb~Para)
plot(Para,Herb)
