Making extra produced schunk globally invisible in Sweave

Question

I'm using ASREML-R for data analysis. When I fit the model in ASREML-R, it produces some information regarding the model like this

dat <- data.frame(y=rnorm(20),x=seq(1,20))
ex.asr <- asreml(y ~ x, data=dat)


asreml(): 3.0.1 Library: 3.01gl IA32  Run: Wed Jan 11 16:53:31 2012

     LogLik         S2      DF
    -13.3387      0.9556    18  16:53:31
    -13.3387      0.9556    18  16:53:31

LogLikelihood Converged 

and even using <<echo=FALSE>>= in Sweave produces this extra Schunk

\begin{Schunk}
\begin{Soutput}

asreml(): 3.0.1 Library: 3.01gl IA32  Run: Wed Jan 11 16:53:31 2012

     LogLik         S2      DF
    -13.3387      0.9556    18  16:53:31
    -13.3387      0.9556    18  16:53:31

LogLikelihood Converged 

\end{Soutput}
\end{Schunk}

I wonder how can I remove this extra information to display in my final output.

Answer 1

echo=FALSE suppresses printing of the input. To hide the output, you need to add results=hide:

<<...,echo=FALSE,results=hide>>=
