Hi, How to unlist list column value and add column into data frame.
Data frame ID ContractDe PassengersDe TrainnerDe 1 list(ConID=c("Zx","78yu"),ConRes = c("98","Tut")) list(PassID =1,PassIt="Lits,uy") list(Trnid=1,Trncont =5,EmpAddInfo=list(list(CohID ="pi",InVoice=77))) 2 list(ConID=c("Half","Yut","Weq"),ConRes =c("ref","Cr")) list(PassID =c("pfil","Q"),Name ="Tic",PassIt="S5,Y1 list(Trnid=7,Trncont =3,EmpAddInfo=list(list(CohID =c("AB","NI","OL"),InVoice = c("4","Y")))) 3 list(ConID=c("Ui","pric"),ConRes = c("Num","Patch")) list(PassID =1,PassIt ="St,Bp") list(Trnid=c("U", "l"),Trncont=c("10","78"),EmpAddInfo=list(list(CohID =c("AB","NI","OL"),InVoice =c("4","Y")))) 4 list(ConID=c("2","7","IO"),ConRes = c("Res","Qty"),ConVal =c("Wno", "ip")) list(PassID =1,Name ="RT",Name1 ="RR",PassIt="st7,st9") list(Trnid=c("1", "3"),Trncont=c("yt","re"),EmpAddInfo=list(list(CohID =c("Ly","qp"),InVoice =c("2","P")))) Expected data frame.
