Dear Group
I have to populate a column in a R dataframe containing say 99 rows, where 
for every 3 row one row (randomly determined) of the column should take 
the value 1 and the other 2 row of that column should take the value 0.
I used the command
dataframe$new<-rep(sample(c(0,1,0),3,replace=FALSE),99)
This command repeats the same patter of response across the entire 
column..
I would rather want the response be randomly populated in every set of 3 
rows..
Eg. if the first row of that column has 0 and the second row of that 
column takes a value of 1 and third row of that column takes 0 again,
for the next 3 rows of that column i would want this order differently say 
1,0,0 and so on..
Can anybody help how i can acheive this.
Thanks.
Regards
Vijayan Padmanabhan
