buildPathwaySpace

<code>buildPathwaySpace</code> is a constructor of
PathwaySpace-class objects.

For a given graph containing vertices, edges, and a signal associated with the vertices, the 'PathwaySpace' package performs a convolution operation, which involves a weighted combination of neighboring vertices and their associated signals. The package then uses a decay function to project these signals, creating geodesic paths on a 2D-image space. 'PathwaySpace' could have various applications, such as visualizing and analyzing network data in a graphical format that highlights the relationships and signal strengths between vertices. It can be particularly useful for understanding the influence of signals through complex networks. By combining graph theory, signal processing, and visualization, the 'PathwaySpace' package provides a novel way of representing and analyzing graph data.

buildPathwaySpace function

<dl><dt>g</dt>
<dd>An <code>igraph</code> object. It must include graph
layout information, with vertex coordinates assigned to <code>x</code> 
and <code>y</code> vertex attributes. It must also include vertex labels 
assigned to the <code>name</code> vertex attribute.</dd>
<dt>nrc</dt>
<dd>A single positive integer indicating the number of rows and 
columns (in pixels) for a square image matrix. This argument will 
affect the resulting image size and resolution.</dd>
<dt>mar</dt>
<dd>A single numeric value (in <code>[0,1]</code>) indicating the size of
the outer margins as a fraction of the image matrix.</dd>
<dt>verbose</dt>
<dd>A single logical value specifying to display detailed 
messages (when <code>verbose=TRUE</code>) or not (when <code>verbose=FALSE</code>).</dd></dl>

Arguments

Vinicius Chagas, Victor Apolonio, Mauro Castro,
and TCGA Network.
