R Markdown to HTML
In microplot: Microplots (Sparklines) in 'LaTeX', 'Word', 'HTML', 'Excel'

This is an example of an Rmarkdown file. Run the irisRMarkdownHtml.Rmd file through rmarkdown::render to create file irisRMarkdownHtml.html file.

Table \ref{irisBW5num} was generated by the \verb:``r: chunk and included in thisRmd` file.

The file was run by rmarkdown::render("irisRMarkdownHtml.Rmd", output_file="irisRMarkdownHtml.html") system(paste("open", "irisRMarkdownHtml.html"))
