[R] Schoenfeld Residuals with tied data

[Bessy]

Dear all,

I am struggling with calculation of Schoenfeld residuals of my Cox Ph
models.

Based on the formula as attached, I calculated the Schoenfeld residuals for
both non tied and tied data, respectively.

And then I validated my results with R using the same data sets. However, I
found that my results for non-tied data was ok but the results for tied data
were different from R's. 

How does R calculate the Schoenfeld Residuals for tied data? Could someone
give me some hints, please?

Thank you so much.
