I'm having problems getting C++ code (written via the cxxfunction in the inline package) to display nicely when using knitr. Here's a MWE:
<html>
<body>
<!--begin.rcode
library(Rcpp)
library(inline)
test <- cxxfunction(signature(xR="numeric"), body="
double x = as<double>(xR);
return(wrap(x));
", plugin="RcppArmadillo")
end.rcode-->
</body>
</html>
When I knit this code, it reformats the body argument by replacing all new lines with "\n" and it makes it very hard to read. Are there any work-arounds to this?
There was a major change as listed in the release notes of knitr 1.6: the default chunk option tidy = TRUE was changed to FALSE. That is why your line breaks are no longer turned to literal \n's with knitr 1.6.
