ch7lie: LIE Data for the Vectorized Root System of a Young Oak Tree
Description
This data set 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.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 (truedenotes the start of a branching link whilefalsedenotes the start of a continuing link).
- Apic: the apical state (truedenotes a point ending a root whilefalseis 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.
