mtgplant2 {dad}

Class foldermtg

Description

These data provides the topology of a bushy plant.

Usage

data("mtgplant2")

Format

This object of class foldermtg is a list of 9 data frames:

• mtgplant2$classes: data frame with 6 rows and 5 columns named SYMBOL (factor: the classes of the vertices), SCALE (integer: the scale at which they appear), DECOMPOSITION (factor), INDEXATION (factor) and DEFINITION (factor).

  The vertex classes are:

  • P: the whole plant (scale 1)

  • A: the axes (scale 2)

  • F, I: the flower and internodes (scale 3)

• mtgplant2$description: data frame with 4 rows and 4 columns (factors) named LEFT, RIGHT, RELTYPE and MAX.

• mtgplant2$features: data frame with 9 rows and 2 columns (factors) named NAME and TYPE.

• mtgplant2$topology: data frame with 14 rows and 3 columns:

  • order1 and order2 (factors): the codes of the vertices, as they are found in the MTG table of the MTG file. The column on which a code appears gives the branching order of the corresponding vertex.

  • vertex (character): the same codes of vertices, on a single column.

• mtgplant2$coordinates: data frame with 0 rows and 0 columns (there are no spatial coordinates in these MTG data).

• mtgplant2$P, mtgplant2$A, mtgplant2$F and mtgplant2$I: data frames of the features on the vertices (all numeric).

Details

This object of class foldermtg can be built by reading the data in a MTG file (see examples).
