Description
The orchids data.frame has 500 rows and 7 columns
Usage
orchids
Format
This data.frame contains the following columns:
measure.ID Number of observation (from Ahmes).
orchid.ID Identification of the orchid.
organ Tags each observation with "leaf" or "pseudobulb".
module Identifies the leaf-pseudobulb pair.
pitch Pitch angle in degrees.
roll Roll angle in degrees.
course Course angle in degrees.
Details
Subset of the dataset in Ventre-Lespiaucq et al. (2017). These data are measurements of three leaf position angles of 250 leaf-pseudobulb pairs in 84 epiphytic orchids (Rodriguezia granadensis). Each row contains either pseudobulb or leaf angle data.
