Main Menu 4-WAY DATA
GGEbiplot provided options to dissect a year-location-genotype-trait 4-way table or a environment-by-genotype-by-trait 3-way data into the following two-way tables and corresponding biplots:
Trait Association By Environment (TABE) biplots
Compound two-way biplots
Year-by-location biplot for any trait
For 3-way and 4-way data with traits in parallel columns, these biplots and ANOVA options are also available.
Note: For 3-way datasets or 4-way datasets with fewer than 2 years, the year-related two-way biplot options will not be available because a biplot with the year as one way requires at least 3 years.
