# rank nodes based on the inward links/outward links/both links

### Description

rank each node in the graph based on their connection status with other nodes, the standard is the inward/outward link numbers.

### Usage

1 | ```
rank.nodes(gemat, type = "both")
``` |

### Arguments

`gemat` |
standard square graph matrix |

`type` |
if type="both", the function will rank the nodes based on total link number, by counting both inward and outward links for each node; if type="in", the function will rank the nodes based on inward link number for each node; if type="out", the function will rank the nodes based on outward link number for each node; |

### Value

return the sorted node vector in decreasing form with names showing the nodes,while the vector elements are the link numbers.
