vol2: Biogas Volume from Batch Reactors

Description

Biogas volume measurements from 15 batch reactors.

Usage

data("vol2")

Format

A data frame with 216 observations on the following 4 variables:

bottle

identification code, a unique value for each reactor in the dataset. A factor with levels 1_1, 1_2, 1_3, 2_1, 2_2, 2_2, ... through 5_3. The first number indicates the sample, the second the replicate.

days

elapsed time of mass measurements (from reactor setup) in days, a numeric vector.

meas.vol

volume of biogas removed at days 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 or 1000 mL glass serum bottles with butyl rubber septa and screw caps. Volume was measured using syringes. Data in vol2, xCH42, and setup2 are from the same reactors.
