Do you want to mimic some C style programming? If yes you'd rather consult 
some documentation coming with R.

Without knowing much about your code the warning message tells you that 
you want to fill six position egg holder with 10 eggs and R correctly 
tells you a warning that it put 6 eggs in the holder and threw away 
remaining four. 

If this is what you intended, you does not need to worry. If you wanted 
something different you need to reveal some more info to us.

x<-1:5
z<-rep(NA, 4)
z[1:4]<-x
Warning message:
In z[1:4] <- x :
  number of items to replace is not a multiple of replacement length
