Render tags into HTML

Source: R/tags.R
renderTags.Rd

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.)

Usage

renderTags(x, singletons = character(0), indent = 0)

doRenderTags(x, indent = 0)

Arguments

x

Tag object(s) to render

singletons

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.)

indent

Initial indent level, or FALSE if no indentation should be used.

Value

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.

Details

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.
