具有对数y比例和负值的图

Question

I have a set of data with both negative and positive values. I would like to present them on a plot with y axis in logarithmic scale. As some of the values are negative, log="y" doesn't work. How to overcome this?

Answer 1

Thank you all for your comments. I've solved the problem by myself: instead of using simple plot() for generating the graph, I've used ggplot2 package with scale_y_log() function to present linear units at logarithmic scale (including negative values).

However, I have one more - similar - question, which can be found here.
