[R] How to disable output messages (prints or cats) from functions in R?

Hi everybody,

I have to use a function that shows an output message like "# nonzero 
coefficients ..." followed with a lot of numbers depending on the input. 
This is very annoying because I have to run that function several times 
and I don't want to show this information.

What I want is to disable that display but I don't know how to do it. 
I've tried it with suppressWarnings ( function (...) ) and 
suppressMessages ( function (...) ) but It doesn't work, the function() 
continues printing that information. I tried invisible () too.

Furthermore, this function doesn't have a "verbose" parameter. Thus, I 
can't disable it using a verbose parameter.

I'm sure that there must be some procedure in R to do it but after 
searching through the mailing lists I haven't found anything about it.

Thank you for your help,
Miguel Ratón Almansa
