Statistics Question

[vanhoesens]

I am a relatively new user with R (using RStudio) and I am using this package for a medical image reconstruction study. The study is forced mark LROC and all of the code is working fine. My question is about the statistics of the calculations made in the code. I am using PlotEmpiricalOperatingCharacteristics and I noticed that it calls multiple levels of functions that cannot be directly accessed in the package. I know they can be found with 'getAnywhere' but these functions do not have documentation or much commenting. When I plot LROC data with floating point scores, how is the program binning that data? I am getting a step function graph so I know that there is some binning but I have not been able to track down exactly how that is decided. Thanks, Sarah
