Hello all , I have a data frame like this X1X2X3 11815 22916 331017 441118 551219 661320 771421 now i want to randomly reorder the variable X2 but the row element should be same as for example X1X2X3 12916 251219 331017 471421 561320 61815 741118 how can i do that ?? Hint : this could be helpful : if X2 is only a vector like this X2<-c(8,9,10,11,12,13,14) so i can easily reorder it by using sample commend sample (X2 , size=length(X2), replace=FALSE)
Yes, and then replace X2 with your reordered X2. Uwe Ligges
may be i have to use lapply commend with sample commend . /.......Tanvir Ahamed [[alternative HTML version deleted]]
