This is an example of an {\tt Rmarkdown} file. Run the {\tt irisMarkdown.Rmd} file through {\tt knit} to create file {\tt irisMarkdown.md} file, which despite its name, is actually a {\tt tex} file. The {\tt irisMarkdown.md} file can be included in a larger tex document. Or the {\tt irisMarkdown.md} file can be converted directly to a {\tt pdf} file with the {\tt Hmisc::dvi} function.

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

The file was run by \begin{verbatim} knitr::knit("irisMarkdown.Rmd") latexSetOptions() dvi(irisMarkdown.latex, width=8.5, height=11, nomargins=FALSE) \end{verbatim}
