Read

Read nodes and edges into your graph, with or without a delay.

sg_read_nodes(sg, data, ..., delay)

sg_read_edges(sg, data, ..., delay)

sg_read_exec(sg, refresh = TRUE)

Arguments

sg	An object of class sigmajsas intatiated by sigmajs.
data	Data.frame (or list) of nodes or edges.
...	Any column name, see details.
delay	Column name containing delay in milliseconds.
refresh	Whether to refresh the force layout.

Functions

• sg_read_nodes read nodes.

• sg_read_edges read edges.

• sg_read_exec send read nodes and edges to JavaScript front end.

Examples

nodes <- sg_make_nodes(50)
 nodes$batch <- c(
         rep(1000, 25),
         rep(3000, 25)
        )

edges <- data.frame(
 id = 1:80,
         source = c(
          sample(1:25, 40, replace = TRUE),
                sample(1:50, 40, replace = TRUE)
         ),
         target = c(
          sample(1:25, 40, replace = TRUE),
                sample(1:50, 40, replace = TRUE)
         ),
         batch = c(
          rep(1000, 40),
                rep(3000, 40)
         )
