Arguments

g

igraph Cnet object

nodes

character vector of one or more Set nodes.

x, y

numeric values passed to nudge_igraph_node().

use_grep

logical passed to nudge_igraph_node().

do_reorder

logical indicating whether nodes should be re-positioned within each subcluster by calling reorderIgraphNodes().

spread_labels

logical indicating whether labels should be re-oriented around each node by calling spread_igraph_labels().

repulse

numeric value passed to layout_with_qfr() to indicate the repulsion force. Typical values range between 3 for loosely-packed nodes, and 5 or higher for more closely-packed nodes.

verbose

logical indicating whether to print verbose output.

...

additional arguments are passed to functions nudge_igraph_node(), layout_with_qfr(), spread_igraph_labels(), reorderIgraphNodes().

Details

This function operates on a Cnet igraph object, distinguished by node attribute "nodeType" with value "Gene" for Gene nodes, and "Set" for Set nodes.

This function is intended to help move a Set node to improve visual spacing between nodes, then it re-positions only the Gene nodes using layout_with_qfr(), keeping the Set nodes in fixed positions.

It calls nudge_igraph_node() using arguments nodes,x,y, then defines the layout coordinates of Set nodes as constraints that therefore are not allowed to change when calling layout_with_qfr(). Note that Gene node coordinates are allowed to change, even if Gene nodes were included in nodes.
