Potato cell-line growth data set

Description

Example data set for analysing growth curves with opm containing manually entered fresh-mass and dry-mass measurements over time from three distinct potato (Solanum tuberosum) cell lines under several stress treatments.

Format

Data frame with 540 rows and six columns. The columns are:

Genotype

Factor containing the names of the cell lines. See Vaas et al. (2013) for further details.

Treatment

Factor describing the three applied stress conditions. There is also one level for the control.

Replicate

Integer vector with the number of the replicate. There are five replicates per combination of ‘Genotype’ and ‘Treatment’.

Time

Integer vector containing the measurement times in days.

FM

Integer vector containing the fresh-mass measurements in milligramme.

DM

Integer vector containing the dry-mass measurements in milligramme.

Details

How to convert and analyse this data set is explained in the vignette on working with growth curves in opm.
