Description Usage Arguments Value Author(s) References See Also Examples

An organizational chart that supports selection.

The gvisOrgChart 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. The actual chart is rendered by the web browser.

1 2	gvisOrgChart(data, idvar = "", parentvar = "", tipvar = "", options = list(), chartid)

`data`	a `data.frame`. The data has to have at least three columns. Each row in the data table describes one node (a rectangle in the graph). Each node (except the root node) has one or more parent nodes. Each node is sized and colored according to its values relative to the other nodes currently shown.
`idvar`	column name of `data` describing the ID for each node. It should be unique among all nodes, and can include any characters, including spaces. This is shown on the node. You can specify a formatted value to show on the chart instead, but the unformatted value is still used as the ID.
`parentvar`	column name of `data` that match to entries in `idvar`. If this is a root node, leave this `NA`. Only one root is allowed.
`tipvar`	column name of `data` for the tip variable. Tool-tip text to show, when a user hovers over this node.
`options`	list of configuration options for Google Org Chart. `gvis.editor` a character label for an on-page button which opens an in-page dialog box that enables users to edit, change and customise the chart. By default no value is given and therefore no button is displayed. Further possible components are, taken from https://google-developers.appspot.com/chart/interactive/docs/gallery/orgchart.html#Configuration_Options: `allowCollapse` Boolean. Default `FALSE`. Determines if double click will collapse a node. `allowHtml` Boolean. Default `FALSE`. If set to `TRUE`, names that includes HTML tags will be rendered as HTML. `nodeClass` A string. Default default class name. A class name to assign to node elements. Apply CSS to this class name to specify colors or styles for the chart elements. `selectedNodeClass` A string. Default class name. A class name to assign to selected node elements. Apply CSS to this class name to specify colors or styles for selected chart elements.
`chartid`	character. If missing (default) a random chart id will be generated based on chart type and `tempfile`
