R ggplot2: using stat_summary (mean) and logarithmic scale

Question

I have a bunch of measurements over time and I want to plot them in R. Here is a sample of my data. I\'ve got 6 measurements for each of 4 time points:

value         


        

Answer 1

scale_y_log2() will do the transformation first and then calculate the geoms.

coord_trans() will do the opposite: calculate the geoms first, and the transform the axis.

So you need coord_trans(ytrans = "log2") instead of scale_y_log2()
