mtgplant1: Class 'foldermtg'

In dad: Three-Way / Multigroup Data Analysis Through Densities

Class foldermtg

Description

These data produced by the SAGAH team (Sciences Agronomiques Appliquées à l'Horticulture, now Research Institute on Horticulture and Seeds), provide the topological structure of a rosebush.

Usage

data("mtgplant1")

Format

This object of class foldermtg is a list of 10 data frames:

• mtgplant1$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)

  • O, M, I: the ..., metamers (phytomers) and inflorescences (scale 3)

• mtgplant1$description: data frame with 8 rows and 4 columns (factors) named LEFT, RIGHT, RELTYPE and MAX.

• mtgplant1$features: data frame with 13 rows and 2 columns (factors) named NAME and TYPE.

• mtgplant1$topology: data frame with 88 rows and 4 columns:

  • order1, order2 and order3 (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.

• mtgplant1$coordinates: data frame with 86 rows and 6 columns (numeric) named XX, YY and 22: cartesian coordinates of the vertices, and AA, BB and CC: an other coordinates system.

• mtgplant1$P, mtgplant1$A, mtgplant1$M, mtgplant1$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).
