grid.element {gridSVG}

Create a grid grob representing an SVG element

Description

Creates a element.grob object which is a grid gTree, representing an SVG element. Useful in conjunction with grid.export, to produce an SVG document with elements inserted at particular points. The element (and its children) are inserted at the point where the grob is “drawn”. Text can be inserted in a similar manner with grid.textNode.

Usage

grid.element(el, name = NULL, attrs = NULL,
             namespace = NULL, namespaceDefinitions = NULL,
             children = NULL, vp = NULL,
             childrenvp = NULL, asis = FALSE)
elementGrob(el, name = NULL, attrs = NULL,
            namespace = NULL, namespaceDefinitions = NULL,
            children = NULL, vp = NULL,
            childrenvp = NULL, asis = FALSE)
grid.textNode(text, name = NULL, vp = NULL)
textNodeGrob(text, name = NULL, vp = NULL)

Arguments

el

The name of the SVG element to create, e.g. "rect".

text

A single element character vector of text directly into insert into the SVG image.

name

A character identifier.

attrs

A list, where the names are SVG attribute names, and values are the values given to the SVG attributes.

namespace

A character vector specifying the namespace for this new element.

namespaceDefinitions

A character vector or a list with each element being a string.

These give the URIs identifying the namespaces uniquely. The elements should have names which are used as prefixes. A default namespace has "" as the name. The values here are used only for defining new namespaces and not for determining the namespace to use for this particular element.

children

A gList object containing children of this element (if any).

vp

A viewport object to draw within.

childrenvp

A viewport object to use for the children of the element grob.

asis

If TRUE, SVG id attributes will be generated from the name with no modification so that we can easily refer to the generated elements.

Value

An element.grob object. For grid.textNode a textnode.grob object.
