R help - Dec 2006 - Demand of help

Hi, 
I'm a phd student of economics in Tunisia who is intersted now with the
seasonal unit roots test of Canova and Hansen. So I've installed the package
"uroot" in RGUI. I use R 2.4.0. The problem when I apply the function
to my data, I've always a message from RConsole that  it is impossible to
find the function CH.test. Are there problems as for the use of this package?
Please help me.
Thank you in advance.
