On this R-data statistics page, you will find information about the tomato data set which pertains to Root weights of tomato plants exposed to 4 different treatments. The tomato data set is found in the DAAG R package. You can load the tomato data set in R by issuing the following command at the console data("tomato"). This will load the data into a variable called tomato. If R says the tomato data set is not found, you can try installing the package by issuing this command install.packages("DAAG") 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 tomato R data set. The size of this file is about 542 bytes.
Root weights of tomato plants exposed to 4 different treatments
tomato data frame has 24 rows and 2 columns. They are from an experiment that exposed tomato plants to four different 'nutrients'.
This data frame contains the following columns:
weight, in g
a factor with levels
2-4-D + conc nutrient,
3x conc nutrient
Dr Ron Balham, Victoria University of Wellington NZ, sometime in 1971 - 1976.
tomato.aov <- aov(log(weight) ~ trt, data=tomato)
tomato.aov <- aov(formula = weight ~ trt, data = tomato)
