您可以通过将NA值替换为0来解决这个问题，如下所示：

mp <- data.frame(time=c(6,6,6,7,10,13,16,22,23,6,9,10,11,17,19,20,25,32,32,34,35,rep(0,7)),trt=c(rep("6-MP",11),rep(NA,19)),event=c(rep(1,11),rep(0,19), 0)) mp

time trt event 1 6 6-MP 1 2 6 6-MP 1 3 6 6-MP 1 4 7 6-MP 1 5 10 6-MP 1 6 13 6-MP 1 7 16 6-MP 1 8 22 6-MP 1 9 23 6-MP 1 10 6 6-MP 1 11 9 6-MP 1 12 10 6-MP 0 13 11 6-MP 0 14 17 6-MP 0 15 19 6-MP 0 16 20 6-MP 0 17 25 6-MP 0 18 32 6-MP 0 19 32 6-MP 0 20 34 0 21 35 0 22 0 0 23 0 0 24 0 0 25 0 0 26 0 0 27 0 0 28 0 0 29 0 NA

现在数据框的行数为29，与时间向量的长度相同
