hie how do you compute the logrank test using R
what commands do you use my data looks something like just an example
treatmentgrp strata censoringTime survivalTime censoring act.surv.time
[1,] 2 2 42.89005 1847.3358 1
42.89005
[2,] 1 1 74.40379 440.3467 1
74.40379
[3,] 2 2 35.17913 344.1113 1
35.17913
[4,] 2 2 55.79590 741.2375 1
55.79590
[5,] 2 1 384.73976 189.7997 0
189.79968
[6,] 1 2 112.76215 375.8227 1
112.76215
[7,] 2 2 20.82441 658.0410 1
20.82441
[8,] 2 2 30.58497 1537.5776 1
30.58497
[9,] 2 1 128.48140 306.9908 1
128.48140
l would like to compare the result with SAS
