Format

An incomplete balanced block design with 4 blocks, 16 treatments, and 5 repetitions, that is, the yield of each treatment is measured 5 times. sorghum is a list with 4 elements. The first x is a factor of lenght 80 with 16 levels describing the treatments. The second dm is data.frame describing the design matrix. Its columns are x, bl (blocks) and r repetitions. The third y is a numeric vector the yields. The fourth dfm is a data frame with four columns. The first tree columns are the design matrix and the fourth is y.

Details

The experiment was conducted at EMBRAPA Milho e Sorgo (The Brazilian Agricultural Research Corporation, Corn and Sorghum section).
