I have a TS of monthly observations.    

 1991(1) 1991(2) 1991(3) 1991(4) 1991(5) 1991(6) 12.00864 11.94203 11.98386 12.01900 12.19226 12.15488

  Now I want to make 11 dummy variables indicating months. Therefore I did followings :    

  For Jan :
  rep(c(rep(0,0), 1, rep(0, 11)), 17)    

  For Feb :
  rep(c(rep(0,1), 1, rep(0, 10)), 17)    

  ........ and so on    

  But my question is there any way to aumate this? Or I have to do the above thing for all 11 months?
