And if you now plot everything exactly as in step 3 above, except having OD on y-axis, here's what [output](doc/tasks/04_out.pdf) should look like.
5. Constrain the OD at limit of detection. You might have noticed on the
previous plot that some of the growth curves start at very low values. In
fact, some of the ODs ended up negative. This is because the values are
actually lower bound by limit of detection (LOD). Experience tells that at
OD~595~ with 30 µL/well in LB, the limit of detection is ~0.03. So the
final step for deriving background subtracted ODs is to constrain OD at
0.03. Multiple ways are again possible, I would go for `ifelse` statement.
