- Ran
sbf()from caret package (for 100 iterations) - Computed ROC value
- Plot ROC (As they are stair steps), need to smooth 100 roc objects.
For smoothing an ROC object, tried 10 iterations The function created checks if there are more than 1 finite value rows in data frame of sp, se. If there are more than 1 row with finite values, the smoothing of roc object happens, else it returns the same roc object as it is without smoothing. 10 iterations runs successfully sometimes, some being smooth roc objects and others roc object. But when I run 10 iterations again, the following error comes
Error in if (is.unsorted(roc$specificities)) { :
missing value where TRUE/FALSE needed
Have checked the smooth.roc.binormal function. I see that there is qnorm() function being used and that how many rows are there with finite values in dataframe of sp and se.
I am not sure where the above error occurs or at what step the is.unsorted(roc$specificities) is checked.
Presently, I have 100 roc objects with me as a list. The function may result in few smoothed roc objects and others being roc object itself as it is.
Expected Output for 100 iterations
Where should I check the above error in my function, as it stops the process of smoothing/non smoothing of roc object.
