gvisMerge: Merge two googleVis charts into one gvis-object

Description

gvisMerge merges two gvis-objects, either next or below each other into one gvis-object. The objects are arranged in a HTML table.

Usage

gvisMerge(x, y, horizontal = FALSE,
                tableOptions = "border="0"", chartid)

Arguments

x

a gvis-object.

y

a gvis-object.

horizontal

boolean. Default FALSE. If FALSE the two gvis-objects are arranged below each other, otherwise next to each other.

tableOptions

a valid HTML table option string. Default "border="0"".

chartid

character. If missing (default) a random chart id will be generated based on chart type and tempfile

Value

• gvisMerge returns list of class "gvis" and "list". An object of class "gvis" is a list containing at least the following components:
• type
  Google visualisation type, here 'gvisMerge'
• chartid
  character id of the chart object. Unique chart ids are required to place several charts on the same page.
• html
  a list with the building blocks for a page [object Object],[object Object],[object Object],[object Object]
