MDSnet function

MDSnet

Convenience function for converting a qgraph object to a layout determined by multidimensional scaling

MDSnet(
  qgraph_net,
  type = c("ordinal", "interval", "ratio", "mspline"),
  MDSadj = NULL,
  stressTxt = F,
  repulse = F,
  repulsion = 1,
  mdsArgs = list(),
  ...
)

Arguments

• qgraph_net: an object of type qgraph
• type: transformation function for MDS, defaults to "ordinal"
• MDSadj: to use a proximities matrix other than the adjacency matrix stored in qgraph_net, provide it in this argument
• stressTxt: logical. Print the stress value in the lower left corner of the plot?
• repulse: logical. Add a small repulsion force with wordcloud package to avoid node overlap?
• repulsion: scalar for the repulsion force. Larger values add more repulsion
• mdsArgs: additional arguments in list format passed to smacof::mds
• ...: additional arguments passed to qgraph

Details

A network plotted with multidimensional scaling can be interpreted based on the distances between nodes. Nodes close together represent closely associated nodes, whereas nodes that are far apart represent unassociated or negatively associated nodes.
