Arguments

A dataframe containing the links. This should consists of two columns: source and target. These should be populated with names that are in the names column of the nodes table.

links.df<-data.frame(source=c("Dan", "Digby", "Flamer"), target=c("Lex", "Flamer", "Stripey"))
link_weights.df<-data.frame(source=c("Dan", "Digby", "Flamer"), target=c("Lex", "Flamer", "Stripey"), weight=c(0.2, 0.3, 0.9))
jsonNodesLinks(nodes.df, links.df)
