Arabidopsis clipping/fertilization data
Data on genetic variation in responses to fertilization and simulated herbivory in Arabidopsis
data("Arabidopsis")A data frame with 625 observations on the following 8 variables.
regregion: a factor with 3 levels NL
(Netherlands), SP (Spain), SW (Sweden)
popupopulation: a factor with the form n.R
representing a population in region R
gengenotype: a factor with 24 (numeric-valued) levels
racka nuisance factor with 2 levels, one for each of two greenhouse racks
nutrientfertilization treatment/nutrient level (1, minimal nutrients or 8, added nutrients)
amdsimulated herbivory or "clipping" (apical meristem
damage): unclipped (baseline) or clipped
statusa nuisance factor for germination method
(Normal, Petri.Plate, or Transplant)
total.fruitstotal fruit set per plant (integer)
