Try the following options

1. echo=FALSE hides the code but displays results 2. results=‘hide’ hides the results but shows the code 3. eval=FALSE displays the code but does not evaluate it 4. include=FALSE evaluates the code but does not display code or output 5. warning=FALSE and message=FALSE are useful for suppressing any messages produced when loading packages
