toDotWithRI {graph} | R Documentation

## Translate a graph to "dot" including rendering information

### Description

The function takes a graph object and translates it into the dot format. All rendering information is written verbatim into the dot graph as well

### Usage

    toDotWithRI(graph, graph_name = NULL, subGraphList = list(),
      isStrict = TRUE)

### Arguments

`graph` | An object of graph `graph`
`graph_name` | The name of the graph
`subGraphList` | A list of objects of class `graph`. Each of these is used as a subgraph in the graph. The names in the list are taken as the names of the subgraph. If a graph is to be seen as a cluster (i.e. with a box around it), its name has to start with `cluster`.
`isStrict` | Should the graph be strict

### Details

Given a graph object, it is translated into the `dot` language so that it can be rendered using the `graphviz` software. In addition to plotting the graph itself, all the rendering information is being used as well.

`graphRenderInfo` attributes are written as an attribute list after the `graph` statement in dot.

`nodeRendenInfo` attributes are written as attribute lists after each node. If an attribute is constant across all node, a global node attribute is written instead of many individual ones.##' Newlines ##' in attributes do not lead to newlines in labels. In `label`, `headlabel` and `taillabel`, in order to get a newline, right justification or left justification, the two character sequences `\n`, `\r` and `\l` have to be written (i.e. in order to create this in R, the backslash has to be escaped in a string, that is has to be written as a double-backslash).

`edgeRenderInfo` attributes as written as attribute lists after each edge, unless an attribute is constant, then it is written as a global edge attribute.

In general, all attribute values are being wrapped in double-quotes, unless the attibute value start with a `<` and ends with a `>`. In this case it is taken as html content and not wrapped in double quotes (nor are contained newlines escaped).

The resulting graph in dot format is returned as a character vector.

### Value

A character vector with the graph in dot format
