Re: [R] Create NA

Hi tj, May be the following? x <- 1:5 NA*x rep(NA, length(x)) HTH, Jorge On Mon, Mar 22, 2010 at 9:05 PM, tj <> wrote: > > 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 : n

[R] Create NA

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.
