Can someone recommend a package in R that will perform a two-sample Kolmogorov?Smirnov test on left censored data? The package "surv2sample" appears to offer such a test for right censored data and I guess that I can use this package if I flip my data, but I figured I would first ask if there was a package specific to left-censored data.
