guessSVGShape: Determine the shape for an SVG element

In duncantl/SVGAnnotation: Tools for post-processing SVG plots created in R

Description

This function and its methods attempt to determine the shape corresponding to an SVG element.

Usage

guessSVGShape(doc, addShapes = TRUE, recursive = FALSE, ...)

Arguments

doc	the SVG element or the document or list of nodes
addShapes	a logical value that determines whether we add a shape attribute to the node with the determined value. This is useful for post-processing the SVG document
recursive	a logical value. Currently ignored. In the future it will control whether child nodes are also processed.
...	additional parameters for the methods

Value

A character vector giving the names of the determined shapes. If addShapes is TRUE, the XML node(s) is modified too as a side effect.

  dd = svgPlot(plot(1:10, type = "l"))
  rr = getPlotRegionNodes(dd)
  xmlSApply(rr[[1]], guessSVGShape)

  dd = svgPlot(plot(1:10, type = "b"))
  rr = getPlotRegionNodes(dd)
  xmlSize(rr[[1]])
  xmlSApply(rr[[1]], guessSVGShape)


  dd = svgPlot(plot(0:25, pch = 0:25))
  rr = getPlotRegionNodes(dd)
