visNetwork-shiny {visNetwork} | R Documentation

## Shiny bindings for visNetwork

### Description

Output and render functions for using visNetwork within Shiny applications and interactive Rmd documents. With `visNetworkProxy`, you can update your network without redraw in shiny.

### Usage

    visNetworkOutput(outputId, width = "100%", height = "400px")

    renderVisNetwork(expr, env = parent.frame(), quoted = FALSE)

    visNetworkProxy(shinyId, session = shiny::getDefaultReactiveDomain())

### Arguments

`outputId` | : output variable to read from
`width, height` | Must be a valid CSS unit (like `"100%"`, `"400px"`, `"auto"`) or a number, which will be coerced to a string and have `"px"` appended.
`expr` | An expression that generates a visNetwork
`env` | The environment in which to evaluate `expr`.
`quoted` | Is `expr` a quoted expression (with `quote()`)? This is useful if you want to save an expression in a variable.
`shinyId` | single-element character vector indicating the shiny output ID of the network to modify
`session` | the Shiny session object to which the map belongs; usually the default value will suffice

### Details

With `visNetworkProxy`, you can update your network and use various methods :

- "all 'visNetwork' functons" : `visOptions`, `visNodes`, `visEdges`, `visPhysics`, `visEvents`, ...

- `visFocus` : Focus to one or more nodes

- `visFit` : Set view on a set of nodes

- `visUpdateNodes` : Update and add nodes

- `visUpdateEdges` : Update and add edges

- `visRemoveNodes` : Remove nodes

- `visRemoveEdges` : Remove edges

- `visSelectNodes` :Select nodes

- `visSelectEdges` : Select edges

- `visGetNodes` : Get nodes dataset

- `visGetEdges` : Get edges dataset

- `visSetSelection` : Select edges/nodes

- `visNearestNodes` : Get nearest nodes

- `visCollapse` : Collapse nodes

- `visUncollapse` : Uncollpase nodes

- `visSetTitle` : Set and update main, submain, footer

- and also... : `visGetSelectedEdges`, `visGetSelectedNodes`, `visGetSelection`, `visGetConnectedEdges`, `visGetConnectedNodes`, `visRedraw`, `visStabilize`, `visSetData`, `visGetPositions`, `visMoveNode`, `visUnselectAll`, `visGetScale`, `visGetBoundingBox`, `visGetViewPosition`,`visSetOptions`
