networkD3 (version 0.4)

simpleNetwork: Function for creating simple D3 JavaScript force directed network graphs.

Description

simpleNetwork creates simple D3 JavaScript force directed network graphs.

Usage

simpleNetwork(Data, Source = 1, Target = 2, height = NULL, width = NULL,
  linkDistance = 50, charge = -30, fontSize = 7, fontFamily = "serif",
  linkColour = "#666", nodeColour = "#3182bd", opacity = 0.6, zoom = F)

Arguments

Data

a data frame object with three columns. The first two are the names of the linked units. The third records an edge value. (Currently the third column doesn't affect the graph.)

Source

character string naming the network source variable in the data frame. If Source = NULL then the first column of the data frame is treated as the source.

Target

character string naming the network target variable in the data frame. If Target = NULL then the second column of the data frame is treated as the target.

height

height for the network graph's frame area in pixels (if NULL then height is automatically determined based on context)

width

numeric width for the network graph's frame area in pixels (if NULL then width is automatically determined based on context)

linkDistance

numeric distance between the links in pixels (actually arbitrary relative to the diagram's size).

charge

numeric value indicating either the strength of the node repulsion (negative value) or attraction (positive value).

fontSize

numeric font size in pixels for the node text labels.

fontFamily

font family for the node text labels.

linkColour

character string specifying the colour you want the link lines to be. Multiple formats supported (e.g. hexadecimal).

nodeColour

character string specifying the colour you want the node circles to be. Multiple formats supported (e.g. hexadecimal).

opacity

numeric value of the proportion opaque you would like the graph elements to be.

zoom

logical value to enable (TRUE) or disable (FALSE) zooming

Examples

# NOT RUN {
# Fake data
Source <- c("A", "A", "A", "A", "B", "B", "C", "C", "D")
Target <- c("B", "C", "D", "J", "E", "F", "G", "H", "I")
NetworkData <- data.frame(Source, Target)

# Create graph
simpleNetwork(NetworkData)
simpleNetwork(NetworkData, fontFamily = "sans-serif")

# }
