R help - Oct 2007 - Strange results converting string to number

Hi,

I am getting a strange result while converting a string vector into numeric
vector:
> Datas[1]
[1] 37315
> as.numeric(Datas[1])
[1] 2

Can anyone help me??

It would seem that ``Datas'' is a ***factor*** and NOT a ``string  
vector''
(i.e. not a vector of mode character).  There is much (repetitive)  
discussion
on this list of how to convert a factor to a numeric vector.  See FAQ  
7.10.
