[R] data.entry question

[Erin Hodgess]

Dear R People:

When I use data.entry for a new variable, the first entry is a NA

The function works all right, but then I get a Warning message:
> data.entry("xb",Modes="numeric")
Warning message:
NAs introduced by coercion

Since the function works acceptably, should I just ignore the 
warning message, please?

By the way, when I use data.entry on an existing variable, it
works just fine.  No warnings.

R 1.8.1 for Windows.

Thanks in advance for any help!
Sincerely
Erin
