createEdgeData.ggobi {Rggobi} | R Documentation |
This function creates an empty GGobi dataset that can be used
to connect points within another dataset.
The idea is that we create this ``invisible'' dataset
within the GGobi instance.
We don't specify values for the edges in this call, but
use setEdges.ggobi
for this.
createEdgeData.ggobi(numEdges, labels=rep("", numEdges), colors=NULL, .gobi=getDefaultGGobi())
numEdges |
the total number of edges to create |
labels |
the labels for the edges, which can be used in annotating the connections on a plot |
colors |
the colors to use for the edges when displaying them |
.gobi |
the GGobi instance |
An object of class ggobiEdgeDataset
which extends ggobiDataset
.
The edge mechanism in GGobi is very powerful and supports a very general form of linking. As a result, simple uses may appear complex. The idea with this interface is to try to hide the complexity. However, you are advised to read the GGobi and RGGobi manuals to get a better understanding of edges and linking.
