I'm not familiar with ReporteRs, but rmarkdown recently gained powerpoint support, so you can use plotly just like you would in any other output format. One catch is that rmarkdown will attempt to take a screenshot of plotly via webshot, which doesn't support plotly's WebGL-based charts. In that case, you can use the orca() function in plotly to do the image exporting yourself, then use something like knitr::include_graphics() to include the resulting image file.
