Details

If you intend to include more than one of these objects in a single page, use a different prefix string for each one. To use this function in knitr, use the chunk options fig.keep='none' and results = 'asis', then cat() the resulting string to the output. See the vignette for examples. Older browsers (< IE7) are not supported.
