Biogas volume measurements from twelve batch reactors.
Usage
data("vol")
Arguments
Format
A data frame with 288 observations on the following 4 variables:
id
identification code, a unique value for each reactor in the dataset. A factor with levels 2_1, 2_2, 2_3, 2_4, 2_5, 2_6, 2_7, 2_8, 2_9, 2_10, 2_11, and 2_12
date.time
date and time of mass measurement, a POSIXct object.
days
elapsed time of mass measurements (from reactor setup) in days, a numeric vector.
vol
volume of biogas removed at date.time in mL, a numeric vector.
Details
These data are meant to be example data for multiple functions, e.g., stdVol, cumBg, or summBg.
Reactors were 500 mL glass serum bottles with butyl rubber septa and screw caps.
Volume was measured using syringes.
Data in vol, mass, xCH4, and setup are from the same reactors.
