change: Change

In JohnCoene/sigmajs: Interface to 'Sigma.js' Graph Visualization Library

Description

Change nodes and edges attributes on the fly

Usage

sg_change_nodes_p(
  proxy,
  data,
  value,
  attribute,
  rate = c("once", "iteration"),
  refresh = TRUE,
  delay = NULL
)

sg_change_edges_p(
  proxy,
  data,
  value,
  attribute,
  rate = c("once", "iteration"),
  refresh = TRUE,
  delay = NULL
)

Arguments

proxy	An object of class sigmajsProxy as returned by sigmajsProxy.
data	data.frame holding delay column.
value	Column containing value.
attribute	Name of attribute to change.
rate	Rate at chich to refresh takes once refreshes once after all values have been changed, and iteration which refreshes at every iteration.
refresh	Whether to refresh the graph after the change is made.
delay	Optional delay in milliseconds before change is applied. If NULL (default), no delay.

Examples

library(shiny)

nodes <- sg_make_nodes()
nodes$new_color <- "red"
edges <- sg_make_edges(nodes)

ui <- fluidPage(
  actionButton("start", "Change color"),
  sigmajsOutput("sg")
)

server <- function(input, output){

  output$sg <- renderSigmajs({
    sigmajs() %>%
      sg_nodes(nodes, id, size, color) %>%
      sg_edges(edges, id, source, target)
  })

  observeEvent(input$start, {
    sigmajsProxy("sg") %>% # use sigmajsProxy!
      sg_change_nodes_p(nodes, new_color, "color")
  })

}

 if (interactive()) shinyApp(ui, server) # run
