Example data set from growth experiments with different concentrations of antibiotics.
Data frame with the following columns:
identifier of the bacterial strain, D=donor, R=recipient, T=transconjugant.
replicate of the trial.
concentration of the antibiotics (Tetracycline).
time in hours.
bacteria concentration measured as optical density.
This rather 'difficult' data set was intentionally selected to make model fitting by the package more challenging.
## plot data and determine growth rates data(bactgrowth) library(lattice) xyplot(value ~ time | strain + as.factor(conc), data = bactgrowth, groups = replicate)
