R help - Feb 2011 - Conflict with Impulse Response Function

Hello buddies.

I'm trying to use the "granger.test" function wich is included in
MSBVAR
package, but I'm also using the package "var" in order to develop
vector
autorregresion analysis.

Everything is well behaved...but when I'm trying to use the "irf"
function
when I have both libraries open there is a problem, I think R doesn't
recognize if I'm using "irf" included in "var" or
included in MSBVAR.

My first attempt to attack this issue was by defining the class of my
matrices, i.e. for "irf" included in "var" the object needs
to be "varest"
and for "irf" included in "MSBVAR" it needs to be
"VAR", however it doesn't
fix the problem at all.

I think that in order to fix the problem it would be desirable to first open
the library I need (for example ... library(MSBVAR)...) and use the function
"granger.test", then when the result appears, close this library...but
I
don't know how to do this.

How can I do this?

Thanx in advance.

Regards from Mexico.
