I think you don't need to multiply... you need to figure out where
your NAs need to be and then index the vector and assign "NA" to it:

x[1:5] <- "NA"

Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
make us feel like gods.  We are mammals, and have not exhausted the
annoying little problems of being mammals.
