visNetwork-shiny

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
