The brew syntax in knitr is similar to the brew package, but all kinds of
|
|||
|

syntax in the brew package will be treated in the same way in knitr: they are

<% x<-1.234; NULL %>

|
|||
|
|
It chops off the trailing newline.
|
|||
|
|
You can add it to any percent-gt. -%>

|||
|
|
<%% foo <- "fee fi fo fum" %%>
|
|||
|
|
foo is still <%= foo %>.
