William Gosset analyzed data from an experiment comparing the yield of regular and kiln-dried corn.
1 |
A data frame with 11 observations on the following 2 variables.
reg
yield of regular corn (lbs/acre)
kiln
yield of kiln-dried corn (lbs/acre)
Gosset (Student) reported on the results of seeding plots with two different kinds of seed. Each type of seed (regular and kiln-dried) was planted in adjacent plots, accounting for 11 pairs of "split" plots.
These data are also available at DASL, the data and story library (http://lib.stat.cmu.edu/DASL/).

The 'mosaic' package masks several functions from core packages in order to add
additional features. The original behavior of these functions should not be affected by this.
Note: If you use the Matrix package, be sure to load it BEFORE loading mosaic.
