Function to automatically identify closing and opening times of chamber measurents

Description

Function to automatically identify closing and opening times of chamber measurents

Usage

split_chamber(
  data,
  closing_lim = 30,
  opening_lim = -10,
  t_max = 3,
  t_init = 0.1,
  t_min = 2,
  gas = "CO2",
  round_intervall = "1 min",
  adj_openings = T
)

Arguments

data	data.frame with gas concentrations of several chamber measurements
closing_lim	maximal concentration-gradient before closing the chamber
opening_lim	minimal concentration-gradient before opening the chamber
t_max	maximal measurement time (minutes), if time between closing and opening exceeds this time the rest of the measurement will not be included for the calculation of the flux
t_init	initial time (minutes) after closing of the chamber that will be excluded from the calculations
t_min	minimum timespan for each chamber measurement in minutes
gas	name of the gas as character
round_intervall
adj_openings	logical; if TRUE opening times will be adjusted to never be smaller than closing times

Value

input data.frame with colums messid (number of the measurement) and zeit (time in minutes after closing) added

Examples

test <- split.chamber(data,
closing_th = 40,
opening_th = -40,
t_max=Inf,
t_init=0,
t_min=5)
