In bgfanalyzer: Analyze Microbial Biogas Fermentation Data

bgfanalyzer

The goal of bgfanalyzer is to help standardizing the analysis of biogas fermentation data, through a novel S3 object class, the BGF. Th package ships with methods allowing object creation based on external files, object manipulation, as well as visualizing and exporting BGF’s .

Installation

You can install the development version of bgfanalyzer from GitHub with:

# install.packages("pak")
pak::pak("BlackiXP/bgfanalyzer")

Example

The package comes with an example data set ‘LabScaleBiogas’

library(bgfanalyzer)
myBGF <- LabscaleBiogas

#> $ExpParam: 11 experimental paramerters
#> $metaData: 16 meta variables
#> $BioGasData: 735 observations of 7 fermentation variables

The data of a BGF can be plotted with simplest methods:

plot(myBGF)

This plot is produced by the minimum data needed to set up a BGF, the accumulated exhaust gas volumes of each fermentation part of the BGF. Upon further processing, other parameters can be visualized using advanced plotting methods, such as plot_curve() or bgf_plot():

# plot the production
plot_curve(myBGF,production,reactor)

# plot the yield
bgf_plot(myBGF,type="yield_box")
