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)
may be i have to use lapply commend with sample commend .
