Hi Janetta,
It makes some sense, but perhaps not enough. The easy answer would be:


If you mean you want _alternating_ values:


If you want a general solution to the problem of filling a vector of 
arbitrary length with alternating values:

fill_alternating<-function(len=2,value1=0,value2=1) {

There are probably other interpretations as well.
