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"
... which would coerce x to be character while
x[1:5] <- NA
keeps the mode of x.

Hi,
How can I create an NA?
for example, i have this program but it has errors
x=scan()
1: 1 2 3 4 5
6:
Read 5 items
"na"*x
Error in "na" * x : non-numeric argument to binary operator
what should I multiply x so that I will get an NA? And I really need to
multiply that with my x vector.
I need this output: (na,na,na,na,na)
Thank you for your time and help!=)
