The plot (Output 21.6.4) in the above link shows the # of subject at risk at different time point. I was able add a horizontal label on the left side of the lower panel, e.g. At Risk, I was hoping to change it to a vertical label, does anyone know how to do that?
The same plot also shows the survival probability as label on the y-axis. Is there a way to change it to percentage and give an appropriate label? Therefore 10, 20, ... 100 (%)
