A HTML vignette is a lightweight alternative to html_document
suitable for inclusion in packages to be released to CRAN. It reduces the
size of a basic vignette from 100k to around 10k.
html_vignette(fig_width = 3, fig_height = 3, dev = "png",
df_print = "default", css = NULL, keep_md = FALSE, readme = FALSE,
...)Default width (in inches) for figures
Default width (in inches) for figures
Graphics device to use for figure output (defaults to png)
Method to be used for printing data frames. Valid values
include "default", "kable", "tibble", and "paged". The "default" method uses
print.data.frame. The "kable" method uses the
knitr::kable function. The "tibble" method uses
the tibble package to print a summary of the data frame. The "paged"
method creates a paginated HTML table (note that this method is only valid
for formats that produce HTML). In addition
to the named methods you can also pass an arbitrary function to be used
for printing data frames. You can disable the df_print behavior entirely
by setting the option rmarkdown.df_print to FALSE.
One or more css files to include
Keep the markdown file generated by knitting.
Use this vignette as the package README.md file (i.e. render it as README.md to the package root). Note that if there are image files within your vignette you should be sure to add README_files to .Rbuildignore
Additional arguments passed to html_document. Please
note that theme, fig_retina and highlight are hard
coded. Setting any of those will yield an error.
R Markdown output format to pass to render
Compared to html_document, it:
never uses retina figures
never uses a theme
has a smaller default figure size
uses a custom css stylesheet
uses a custom highlight scheme
See the online
documentation for additional details on using the html_vignette format.
