Hello I'm a newbie to the R program and I have problems to plot two functions in one plot window. I know that I can use the plot command for the first function and the lines command for the second function but the problem is that the first function has only values beginnig from 1 to 7 on the x-axis and the second function values from 2 to 8. When I plot the second function with "lines" in the plot, it is drawn beginning at 1 and that is wrong because it should start at 2. Is there a parameter where you can define the start on the x-axis? Thanks for help Markus
