"Hello, I am a doctoral student in oncology. Thank you very much for your R package, condsurv, which can be well utilized to estimate conditional survival probabilities and plot conditional survival probability survival curves. However, there is a common application in the field of oncology, which involves comparing the conditional survival probabilities of patients after a specified time point post-surgery. This entails comparing the survival curves of conditional survival probabilities after the specified time point with those of other known groups, for example, through the logrank test. I am wondering if your package can achieve this. Thank you.
