Description Usage Arguments Value Author(s) References See Also Examples

Limit a list of network motifs as returned by the motifStatsVAR1-function to those involving a particular node.

1	pruneMotifStats(motifList, id)

`motifList`	A `list` with motifs as returned by the `motifStatsVAR1`-function.
`id`	A `integer` representing the node of interest.

An object of class list with slots:

`selfregulators`	A `list` of motifs specified as matrices with each row one of the motif's paths and in the last column the sign of the path's contribution.
`feedbackpairs`	A `list` of motifs specified as matrices with each row one of the motif's paths and in the last column the sign of the path's contribution.
`feedforwardloops`	A `list` of motifs specified as matrices with each row one of the motif's paths and in the last column the sign of the path's contribution.
`feedbackloops`	A `list` of motifs specified as matrices with each row one of the motif's paths and in the last column the sign of the path's contribution.
`bifans`	A `list` of motifs specified as matrices with each row one of the motif's paths and in the last column the sign of the path's contribution.
`diamonds`	A `list` of motifs specified as matrices with each row one of the motif's paths and in the last column the sign of the path's contribution.

Future versions of this function may include additional slots reporting more motif types.
