ch7lie: LIE Data for the Vectorized Root System of a Young Oak Tree
Description
This dataset obtained with Data Analysis of Root Tracings summarizes the attributes of each point used to construct the links constituting the interpreted root system of a young oak tree (Quercus robur L.) growing in a vertical rhizobox.
Usage
ch7lie
Arguments
Format
A data frame containing the following columns:
Num: the identification number of each point (i.e. the junctions between two consecutive links) used to construct the vectorized root system.
Date: the identification number coding for the date at which a point was seen for the first time.
Bran: the branching state (‘true’ denotes the start of a branching link while ‘false’ denotes the start of a continuing link).
Apic: the apical state (‘true’ denotes a point ending a root while ‘false’ is related to a point starting a new link).
Prec: the identification number of the previous point used to construct a link.
Suiv: the identification number of the following point used to contruct a link.
X: the X coordinate of each point used to construct the vectorized root system.
Y: the Y coordinate of each point used to construct the vectorized root system.
