Sugar-cane Disease Data
cane data frame has 180 rows and 5 columns.
The data frame represents a randomized
block design with 45 varieties of sugar-cane and 4 blocks.
The aim of the experiment was to classify the varieties into resistant, intermediate and susceptible to a disease called "coal of sugar-cane" (carvao da cana-de-acucar). This is a disease that is common in sugar-cane plantations in certain areas of Brazil.
For each plot, fifty pieces of sugar-cane stem were put in a solution containing the disease agent and then some were planted in the plot. After a fixed period of time, the total number of shoots and the number of diseased shoots were recorded.
This data frame contains the following columns:
The total number of shoots in each plot.
The number of diseased shoots.
The number of pieces of the stems, out of 50, planted in each plot.
A factor indicating the variety of sugar-cane in each plot.
A factor for the blocks.
