Hi, I am using this sm.survival() to plot smoothed survival curve against a single continuous covariate. I did a logarithmic transformation on the covariate. Now in the plot, I want the tick mark value to be transformed back to original values. For instance, my current x axis tick mark values are 1,2,3,4,5.... . I want them to be like exp(1), exp(2), exp(3), exp(4)....without changing the way the plot look like. I did not find entries of axis tick marks in either sm.options nor sm.survival. Can anyone help me with this? Thank you very much.
