Dear friends, I am working on a double loop using for. One level of loop is to predict N times for each subject, and the second level is to predict M times for the every subject, one subject after one subject. Please note every subject have different N or M rows of data. Any advice? Thank you so much!
Below is the current code: set.seed (123) ## for consistent result; ND <- S004Cmin[S004Cmin$ID %in% c(1:10),] # define the first 10 subjects predSurv <- vector("list", nrow(ND)) for (i in 1:nrow(ND)) { set.seed(123) predSurv[[i]] <- survfitJM(fitJOINT.NULL, newdata = ND[1:i, ], idVar="USUBJID") } Thank you very much!
