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
1 2 | toDotWithRI(graph, graph_name = NULL, subGraphList = list(),
isStrict = TRUE)
|
graph |
An object of graph |
graph_name |
The name of the graph |
subGraphList |
A list of objects of class |
isStrict |
Should the graph be strict |
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.
