Constructs and draws a force directed graph using an "all pairs" association matrix to drive attraction in the graph. This adjacency matrix can represent linear or non-linear associations.

1 |

`dataSet` |
a data frame |

`dataName` |
a string naming the dataSet. (set to NULL if unknown) |

`method` |
one of "A" for non-linear associations or "Rsq" for linear associations. Defaults to "A". |

`cutoff` |
a real number between 0 and 1, used to remove edges from the graph with
association < cutoff.
Defaults to |

`dim` |
graph layouts can be generated in 2 or 3 dimensions. note that |

The `igraph`

package is used to generate, layout and display the force
directed graph. The layout employed is `layout.kamada.kawai`

.

Returns nothing.

All non numeric columns and non complete rows are stripped from the data set before the adjacency matrix is computed.
