Dear Akhilesh, I'm sorry you didn't get a response for a couple of weeks. I use knitr quite extensively, and I just tested and indeed HTML export does not work well. I tried both with built-in LyX's HTML export as well as using an external tool. In theory, the export using LyX's built-in HTML export should be fixable. That said, we would need a developer who is interested enough (if a LyX dev is interested enough, I will be happy to provide examples and testing) and my guess is that won't happen any time soon. Unfortunately, I only have a hackish proposal, which is to try to convert the PDF itself to HTML. I think there are such tools that work reasonably well these days. I don't have experience with them though. Sorry I don't have better news, maybe someone else will. It is quite unfortunate you are "punished" for using the excellent workflow of knitr. Best of luck!
