#as.numeric for emphasis
sprintf('%d', as.numeric(1))
# [1] "1"


sprintf('%d', NA_real_)

>  Error in sprintf("%d", NA_real_) :

   invalid format '%d'; use format %f, %e, %g or %a for numeric object

I understand the error is correct, but if it works for other numeric input,
why doesn't R just coerce NA_real_ to NA_integer_?
