removing plot margins in R

Question

I want to remove the space between the axes of the plot and the plot contents themselves. Any ideas?

Answer 1

Look at the parameters xaxs and yaxs (under ?par). By default the axis contains the data range plus 4% on either side. If you override the parameter, then you can get an axis exactly equal to the data range. Cf:

> curve(x^2)

> curve(x^2, xaxs="i", yaxs="i")
