strawComp: Methane Content of Biogas
In biogas: Process Biogas Data and Predict Biogas Production

Description Usage Format Details Source Examples

Methane content (biogas composition) measurements from 12 anaerobic batch reactors with straw for substrate.

1	data("comp")

A data frame with 63 observations on the following 4 variables.

bottle: identification code, a unique value for each reactor in the dataset. Integer with all values from 1 to 12.
date.time: date and time of mass measurement, a POSIXct object.
time: elapsed time of mass measurements (from reactor setup) in days, a numeric vector.
xCH4: biogas methane content as a mole fraction, excluding water and all other gases other than carbon dioxide, a numeric vector

These data are meant to be example data for cumBg. Reactors were ca. 600 mL glass serum bottles with butyl rubber septa and screw caps. Pressure was measured using an electronic manometer. Data in strawMass, strawSetup, and strawPressure are from the same reactors.
