When using ggplot in R, how do I remove margins surrounding the plot area?

Question

I\'m trying to generate some fractals and have a question regarding the margins with ggplot in R. I\'m using the following code to generate the fractals.

lib

You can also use theme_nothing() from the cowplot package:

require(cowplot)
qplot(1:10, (1:10)^2, geom='line') + theme_nothing() + 
  scale_x_continuous(expand=c(0,0)) +
  scale_y_continuous(expand=c(0,0)) +
  labs(x = NULL, y = NULL)

Unfortunately, you still need to add labs(x = NULL, y = NULL), because there is no way in ggplot2's theme machinery to remove the axes completely. And you need to set expand=c(0,0) in the scale parameters to make sure the scale doesn't extend beyond your data range.

Result:
