Abstract plot

You can do than. You just need to specify the strings in the
axis-labels.

plot(y~x, axes = F)
axis(1, at = range(x), labels = c("Xmin", "Xmax"))
axis(2)

Onderwerp: [R] Abstract plot

I want to make a plot, but instead of showing _numerical_ 
values, I would like to show _symbolic_ values.

For example, I want to plot a function y = a x + b, where x 
varies between Xmin and Xmax. I would like the plot to show, 
in the x-axis, the strings Xmin and Xmax, instead of their 
numeric values. Is it possible?
