Phosphorus plots data from Avolio et al. 2014
Description
A dataset of tallgrass prairie plant composition in a nitrogen and phosphorus addition experiment at Konza Prairie, Manhattan Kansas (Avolio et al. 2014). This dataset is a subset of the full dataset.
Usage
data(pplots)
Format
A data frame with 1232 rows and 6 variables
Details
A data frame containing a column for replicate, year, species, abundance, block and treatment :
plot: An integer column of spatial replicates with 18 levels (6-48)
year: An integer column of sampling time points
species: A factor column of species sampled
relative_cover: A numeric column of relative cover values
block: An integer column of dummy blocking variable, grouping treatment plots into blocks
treatment: A factor column of nitrogen and phosphorus treatments applied to the plots
