[R] latex \subfloat{} incompatible with sweave/knitr code

[Yihui Xie]

Yes that is one possible solution, but the filename is hard-coded
somehow. The key to this problem is a missing new line before <<>>=,
which was addressed in
https://github.com/downloads/yihui/knitr/knitr-subfloats.pdf

The LyX and Rnw source files can be checked out with GIT under
https://github.com/yihui/knitr/tree/master/inst/examples If you open
knitr-subfloats.lyx, you will see an intentional new line in the ERT,
and that is to break \subfloat[asdfa]{<<>>= into

\subfloat[asdfa]{
<<>>=

Regards,
Yihui
