knitr chunk option code to input code into a chunk does not work in R 3.1.1 with knitr 1.6.10

Question

I'm using knitr 1.6.10 in R 3.1.1. The chunk option code seems like does not work. My MWE in .Rnw format is below:

\documentclass{article} \begin{document} << packages, include=FALSE, cache=FALSE>>= library(knitr) library(formatR) @ <<test, code=formatR::usage(lm), eval=FALSE>>= @ \end{document}

Previously this function was working (See here) but it is not working even-though formatR::usage(lm) working outside chunk code.

The answer you mentioned has stated that the formatR version must be >= 0.10.3, which is a development version.
