CWD: Coarse Woody Debris Data

Description

Carbon flux on six pieces of wood.

Usage

data(CWD)

source

L. M. Rowland, C. Stahl, D. Bonal, P. W. Meir, M. Williams (2012). Seasonal variability in respiration from coarse dead wood in a tropical forest.

Details

Aninfra red gas analyser and a clear chamber sealed to the wood surface were used to measure the flux of carbon out of the wood. Measurements were repeated on CWD samples 13 times from July to November 2011, during the transition into and out of the dry season. The aim was to assess if there was shifts in the CWD respiration in response to the shift in the seasons.

Examples

data("CWD")
  CWD[1:6] <- 100 * CWD[1:6] # scaling (to avoid warning)
  maxstat_test(sample2 + sample3 + sample4 +
               sample6 + sample7 + sample8 ~ trend, data = CWD,
               distribution = approximate(1e5))
