Renders tags (and objects that can be converted into tags using
as.tags()) into HTML. (Generally intended to be called from web
framework libraries, not directly by most users--see
print.html() for higher level rendering.)
renderTags(x, singletons = character(0), indent = 0)doRenderTags(x, indent = 0)
renderTags returns a list with the following variables:
head: An HTML() string that should be included in <head>.
singletons: Character vector of singleton signatures that are
known after rendering.
dependencies: A list of resolved htmlDependency() objects.
html: An HTML() string that represents the main HTML that was rendered.
doRenderTags returns a simple HTML() string.
Tag object(s) to render
A list of singleton signatures to consider already rendered; any matching singletons will be dropped instead of rendered. (This is useful (only?) for incremental rendering.)
Initial indent level, or FALSE if no indentation should
be used.
doRenderTags is intended for very low-level use; it ignores
render hooks, singletons, head, and dependency handling, and simply renders the given tag
objects as HTML. Please use renderTags() if x has not already handled its dependencies
and render hooks.
