[R] Reconstruct a dataset

[Lisa]

Supplement to my problem

I know how to generate the random numbers, but I am not sure how to rewrite
the dataset. In my example, for the first set of random number, rn1 <- c(0,
0, 1, 1),  only the last two numbers are “1”s, not zeros, so I select the
individual 3 and individual 4 from y original dataset, i.e., 

2  1
2  2  

And then write these two rows as

id  var1.1  var1.2  var2.1  var2.2  
1        2       2       1       2  

For the second set of random number, rn2 <- c(0, 0, 2, 0), only the third
number is “2”,  so I select the individual 3 two times from my original
dataset, i.e., 

2  1
2  1  

And then write these two rows as

id  var1.1  var1.2  var2.1  var2.2  
2        2       2       1       1  

And so on.

Finally, combine all rows together

id  var1.1  var1.2  var2.1  var2.2  
1        2       2       1       2  
2        2       2       1       1
