RTF, PDF, HTML, and DOCX also support plots produced with the ggplot2
package. Use the create_plot()
function to create plot
content for a report. The plot can be added to the report with the
add_content()
function, just like tables and text.
If you want to add a custom image from another charting package, you
may also pass a path to a JPEG file on the create_plot()
function. The write_report()
function will then get the
image and insert it into the report at the specified location.
