wide figures in a twocolumn article

[Matias Freytes]

Hello,
        This is almost off topic because I'm not using lyx for
this article, I'm using LaTex. I didn't know where else I
could ask. I'm sorry.
        I need to insert a wide eps figure in a twocolumn
IEEEtrans article. I'm using package "graphix". Any ideas?
        Please, cc to my email address because I have "digest
on".


Thanks in advance,
Matias.
