Hi - Below is my code and then the error when I run the last line. time_np <- train1_na$tte event_np <- train1_na$censored X_np <- cbind( train1_na$AMT, train1_na$DISCOUNT_AMT, train1_na$high_price_pcnt, train1_na$EM_RECEIVED, train1_na$DM_RECEIVED, train1_na$TXN_WITH_RINGCODE, train1_na$WEB, train1_na$clearance_pcnt, train1_na$bts_pcnt, train1_na$sales_pcnt, train1_na$holiday_pcnt, train1_na$TXN, train1_na$REDEEMED_REWARDS ) # Kaplan-Meier non-parametric analysis
kmsurvival_np <- survfit(Surv(time_np,event_np) ~ X_np) Error in `[.default`(y, who, 1) : (subscript) logical subscript too long Any ideas? I have tried several things and still get this error.
