Biplot AMMI.
# S3 method for AMMI plot( x, first = 1, second = 2, third = 3, type = 1, number = FALSE, gcol = NULL, ecol = NULL, angle = 25, lwd = 1.8, length = 0.1, xlab = NULL, ylab = NULL, xlim = NULL, ylim = NULL, ... )
x | object AMMI |
---|---|
first | position axis x, 0=Y-dependent, 1=PC1, 2=PC2, 3=PC3 |
second | position axis y,0=Y-dependent, 1=PC1, 2=PC2, 3=PC3 |
third | position axis z,0=Y-dependent, 1=PC1, 2=PC2, 3=PC3 |
type | 1=biplot, 2= triplot |
number | TRUE or FALSE names or number genotypes |
gcol | genotype color |
ecol | environment color |
angle | angle from the shaft of the arrow to the edge of the arrow head |
lwd | parameter line width in function arrow |
length | parameter length in function arrow |
xlab | x labels |
ylab | y labels |
xlim | x limites |
ylim | y limites |
... | other parameters of plot |
type=1 produce graphs biplot. type=2 produce graphs triplot, the components are normalizad in scale 0-1.
