\series bold
knitr
\series default
 is an alternative tool to Sweave based on a different design with more
 features.
 \SpecialChar LyX
 has native support to Sweave since version 2.0.0, and the support to 
\series bold
knitr
\series default
 was also added since 2.0.3.
 The usage is basically the same as the 
\family sans
Sweave
\family default
 module

Note the 
\series bold
knitr
\series default
 package requires R >= 2.14.1, so you need to update R if you are using an
 old version of R.
 Here we show one chunk as a simple example:
