extractDrugVAdjMa {Rcpi} | R Documentation

## Descriptor that Calculates the Vertex Adjacency Information of A Molecule

### Description

Descriptor that Calculates the Vertex Adjacency Information of A Molecule

### Usage

    extractDrugVAdjMa(molecules, silent = TRUE)

### Arguments

`molecules` | Parsed molucule object.
`silent` | Logical. Whether the calculating process should be shown or not, default is `TRUE`.

### Details

Vertex adjacency information (magnitude): 1 + \log_2^m where m is the number of heavy-heavy bonds. If m is zero, then `0` is returned.

### Value

A data frame, each row represents one of the molecules, each column represents one feature. This function returns one column named `VAdjMat`.
