gvisBubbleChart: Google Bubble Chart with R

Description

The gvisBubbleChart function reads a data.frame and creates text output referring to the Google Visualisation API, which can be included into a web page, or as a stand-alone page.

A bubble chart is used to visualize a data set with 2 to 4 dimensions. The first two dimensions are visualized as coordinates, the 3rd as color and the 4th as size.

The bubble chart is rendered within the browser using SVG or VML and displays tips when hovering over points.

                      colorvar = "", sizevar = "",
