Formatting the axis of plot() to shown our own values.

Part 1: I want to plot the CO2 concentration vs. year, but extending the x-axis using the xlim parameter to include the year 2006 (x axis range of values are from -41210 to 0), and adjusting the ylim parameter to go up to 400 when the range of y axis values are from 150 to 300. How do I do this? Using axis function? I am confused about the syntax here.
plot(year,co2,xlim=c(-41210,2006),ylim=c(150,400))
Part 2: I also want to use the points() function to add the data points from years 1958-2006 on X axis to the above plot, but in a different color.
points(...,...,bg="red") Perhaps also col="red" - may depend on what character (pch=..) you are plotting. HTH, Stephan
