I would not have called such an axis "logarithmic" since the logarithm function is bounded below at 0, but I think that what you seek will be found among the examples that accompany Sarkar's book, chapter 8, figures 8.3 - 8.5: http://lmdvr.r-forge.r-project.org/figures/figures.html On Jun

[R] Two-sided log axis

2009-06-10 Thread John Wiedenhoeft
Hi, I have two curves that are best displayed using a logarithmic y-axis. I want to plot the difference of these curves, which means I would need a log scaling on both the negative and the positive side (i.e. the y-axis should be -100 -10 -1 0 1 10 100). Zero values should not be discarded. Is
