Description Usage Arguments Value Examples
This function takes the output of het_cv_glasso
or
mixglasso
and creates a plot of the highest scoring edges along the
y axis, where, the edge in each cluster is represented by a circle whose area
is proportional to the smallest mean of the two nodes that make up the edge,
and the position along the y axis shows the partial correlation of the edge.

net.clustering |
A network clustering object as returned by
|
p.corrs.thresh |
Cutoff for the partial correlations; only edges with absolute partial correlation > p.corrs.thresh (in any cluster) will be displayed. |
hard.limit |
Additional hard limit on the number of edges to display. If p.corrs.thresh results in more edges than hard.limit, only hard.limit edges with the highest partial correlation are returned. |
display |
If TRUE, print the plot to the current output device. |
node.names |
Names for the nodes in the network. |
group.names |
Names for the clusters or groups. |
dot.size.range |
Graphical parameter for scaling the size of the circles (dots) representing an edge in each cluster. |
Returns a ggplot2 object. If display=TRUE, additionally displays the plot.
