eco: Example dataset of light-response curves

In marjoleinF/gamtree: GAM-based Recursive Partitioning

Example dataset of light-response curves

Description

The data comprises light-response curves, which describe the relationship between photosynthetically active radiation (PAR) and photosynthetic rate (Pn). Observations are repeated measures on the same plants. Variable 'Specimen' provides an identifier for individual plants. Dataset was copied from https://stackoverflow.com/questions/37037445/using-mob-trees-partykit-package-with-nls-model For illustrating the funtionality of package gamtree, two variables were added: Specimen, which identifies individual plants, and noise an artificially generated continuous covariate that is pure (gaussian) noise.

Usage

data(eco)

Format

## 'eco' A data.frame with 628 observations of 5 variables:

Species

categorical partitioning variable, indicator for specie (signal).

PAR

continuous predictor variable for the node-specific model (signal).

Pn

continuous response variable.

Specimen

identification number of individual plants.

noise

artifically generated continuous covariate (noise).
