rcx_toNGraph: Deprecated: Create NGraph object from RCX object

Description Usage Arguments Details Value See Also Examples

View source: R/ndex_RCXgraph.r

Description

These functions are provided for compatibility with older versions of ‘ndexr’ only, and will be defunct at the next release.

This function creates an NGraph object from a supplied RCX object. RCX objects store the CX data as a named list of data.frames containing metaData and all aspects of the network. The NGraph class inherits from igraph and contains the complete (R)CX information as graph, node and edge attributes. All igraph functionality is available, e.g. access nodes and edges of igraph g via V(g) and E(g) and their attributes via V(g)$attribute
