adjust_cnet_nodeset: Adjust Cnet node set

In jmw86069/jamenrich: Analysis and Visualization of Multiple Gene Set Enrichments

Adjust Cnet node set

Description

Adjust Cnet node set

Usage

adjust_cnet_nodeset(
  g,
  set_nodes = NULL,
  x = 0,
  y = 0,
  expand = 0,
  percent_spacing = NULL,
  rotate_degrees = 0,
  cnet_nodesets = NULL,
  verbose = FALSE,
  ...
)

Arguments

g	igraph Cnet plot, with vertex attribute nodeType that contains values "Gene" and "Set", as produced by memIM2cnet().
set_nodes	character vector of one or more set names, which are defined here as the names of the nodes with nodeType="Set" to which each node with nodeType="Gene" is connected. For example set_nodes=c("A", "B") will return all Gene nodes that are connected only to Set nodes "A" and "B". Alternatively, one can refer to a cluster by the node name of one member of the cluster, as a convenience option.
x, y	numeric indicating the relative amount to move nodes in the node set, based upon the overall range of x and y values in the layout coordinates.
expand	numeric the relative amount to expand node coordinates, where expand=0 does no expansion, expand=1 will expand coordinates 100% of the distance to the center of the cluster, twice the original distance; and expand=-1 will expand coordinates to half the distance to the center.
rotate_degrees	numeric value indicating the rotation in degrees to adjust the node coordinates, relative to the center of the coordinates.
cnet_nodesets	list optional to provide the known nodesets upfront, in order to avoid re-determining the nodesets.
verbose	logical indicating whether to print verbose output.
...	additional arguments are ignored.

Details

This function is intended to help adjust a node set, defined as a set of "Gene" nodes that all connect to the same "Set" nodes. These nodes are usually clustered together in a Cnet plot, and can be manipulated as a group using this function. Use get_cnet_nodeset(g) to get all node sets from a Cnet igraph object.

Specifically, this function can be used to expand, rotate, and move the cluster of nodes in a Cnet network layout. The purpose is usually to help the visual clarity of the plot, and to reduce node label overlaps.
