On this Picostat.com statistics page, you will find information about the Arabidopsis data set which pertains to Arabidopsis clipping/fertilization data. The Arabidopsis data set is found in the lme4 R package. You can load the Arabidopsis data set in R by issuing the following command at the console data("Arabidopsis"). This will load the data into a variable called Arabidopsis. If R says the Arabidopsis data set is not found, you can try installing the package by issuing this command install.packages("lme4") and then attempt to reload the data. If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the Arabidopsis R data set. The size of this file is about 27,123 bytes.
Arabidopsis clipping/fertilization data
Data on genetic variation in responses to fertilization
and simulated herbivory in Arabidopsis
A data frame with 625 observations on the following 8 variables.
region: a factor with 3 levels
population: a factor with the form
representing a population in region
genotype: a factor with 24 (numeric-valued) levels
a nuisance factor with 2 levels, one for
each of two greenhouse racks
fertilization treatment/nutrient level (1,
minimal nutrients or 8, added nutrients)
simulated herbivory or "clipping" (apical meristem
unclipped (baseline) or
a nuisance factor for germination method
total fruit set per plant (integer)

A comprehensive test of the 'limiting resources' framework applied to
plant tolerance to apical meristem damage.
