bactgrowth {growthrates}

Plate Reader Data of Bacterial Growth

Description

Example data set from growth experiments with different concentrations of antibiotics.

Format

Data frame with the following columns:

strain

identifier of the bacterial strain, D=donor, R=recipient, T=transconjugant.

replicate

replicate of the trial.

conc

concentration of the antibiotics (Tetracycline).

time

time in hours.

value

bacteria concentration measured as optical density.

Details

This rather 'difficult' data set was intentionally selected to make model fitting by the package more challenging.
