Creating group nodes
Headings define sections in the Argdown document. In the argument map, sections are represented as groups of arguments and statements (visualized as grey boxes). By default, the following rules decide to which group a statement or argument belongs:
How groups are assigned to statements and arguments
Statements: If a statement is used in several sections in the Argdown document, it will appear in the group of the section where it was first defined.
Arguments: The same is true for arguments, except for recontructed arguments. In this case the argument belongs to the group of the section in which its (last) premise-conclusion-structure (pcs) was defined.
Let us look at an example. In the following map, two headings were used to define two groups in the argument map. Click on the "Source" button to see how it was done.
Because H2 is a subsection of H1, its group is a child group of H1's group. Notice that argument a is first used in section H1, but is a member of H2's group because it was not defined in H1.
On the other hand, argument b is defined in H1, but it is reconstructed in H2 and reconstructions take precedence over definitions. So b is a member of H2's group.
groupDepth group setting
To understand how the
groupDepth setting works, we need to first define the level of a group:
The group and section level
Let us call the number of ancestors a section or group has its "level", starting with level 1 for a section or group that is not a subsection or child group of another one of its kind. So a subsection has level 2, a subsubsection has level 3 and so on (you can simply count the number of # characters in a heading to get the level of a section).
Sometimes it is useful to use the lowest section levels of an Argdown document for structuring the text, while only using the higher levels to define groups in the argument map. You can achieve that by using the
groupDepth parameter of the group settings. In general, if the following is true for a section, it will be ignored in the map:
If the following is true, a section will not be turned into a group:
sectionLevel <= maxLevel - groupDepth
maxLevel is the maximum section level in the document.
By default, the groupDepth is set to two, which means that it will only use the two highest levels of sections to define groups in the map. If we use three levels, the lowest level will be ignored in the map (
1 <= 3 - 2). If we set the
groupDepth parameter to 1 in the previous example, we get the following result:
isGroup data flag
Sometimes you might want to have even more control over which sections should be used as groups in the argument map.
In this case you can use the
isGroup data flag to explicitely define which sections are defining groups.
isInGroup data flag
If you want to have more control over which statement or argument is in which group, you can use the
isInGroup data flag.
The flag will put the statement or argument in the group of the current section, even if it is used with a statement or argument reference.
Note that it makes only sense to set the flag once to true. If you use it a second time in a second section, the first flag will be overriden.
The flag will also be ignored if the
isGroup flag of the current section is set to false or if the current section is outside of the current
regroup group setting you can completely overwrite the groups derived from headings. By using this method in your config files, you can apply as many arbitrary groupings to the same Argdown document as you like.
