) package
\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

Then insert R code in the document with either

The package website

has full documentation and demos of
\series bold
knitr
\series default
; many of the examples have links to the \SpecialChar LyX
source documents.
\end_layout
\begin_layout Standard
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:
