plot.mgidi: Plot the multi-trait genotype-ideotype distance index

In metan: Multi Environment Trials Analysis

Plot the multi-trait genotype-ideotype distance index

Description

Makes a radar plot showing the multi-trait genotype-ideotype distance index

Usage

## S3 method for class 'mgidi'
plot(
  x,
  SI = 15,
  radar = TRUE,
  type = "index",
  position = "fill",
  rotate = FALSE,
  genotypes = "selected",
  n.dodge = 1,
  check.overlap = FALSE,
  x.lab = NULL,
  y.lab = NULL,
  title = NULL,
  arrange.label = FALSE,
  size.point = 2.5,
  size.line = 0.7,
  size.text = 10,
  width.bar = 0.75,
  col.sel = "red",
  col.nonsel = "gray",
  legend.position = "bottom",
  ...
)

Arguments

x	An object of class mgidi
SI	An integer (0-100). The selection intensity in percentage of the total number of genotypes.
radar	Logical argument. If true (default) a radar plot is generated after using coord_polar().
type	The type of the plot. Defaults to "index". Use type = "contribution" to show the contribution of each factor to the MGIDI index of the selected genotypes/treatments.
position	The position adjustment when type = "contribution". Defaults to "fill", which shows relative proportions at each trait by stacking the bars and then standardizing each bar to have the same height. Use position = "stack" to plot the MGIDI index for each genotype/treatment.
rotate	Logical argument. If rotate = TRUE the plot is rotated, i.e., traits in y axis and value in the x axis.
genotypes	When type = "contribution" defines the genotypes to be shown in the plot. By default (genotypes = "selected" only selected genotypes are shown. Use genotypes = "all" to plot the contribution for all genotypes.)
n.dodge	The number of rows that should be used to render the x labels. This is useful for displaying labels that would otherwise overlap.
check.overlap	Silently remove overlapping labels, (recursively) prioritizing the first, last, and middle labels.
x.lab, y.lab	The labels for the axes x and y, respectively. x label is set to null when a radar plot is produced.
title	The plot title when type = "contribution".
arrange.label	Logical argument. If TRUE, the labels are arranged to avoid text overlapping. This becomes useful when the number of genotypes is large, say, more than 30.
size.point	The size of the point in graphic. Defaults to 2.5.
size.line	The size of the line in graphic. Defaults to 0.7.
size.text	The size for the text in the plot. Defaults to 10.
width.bar	The width of the bars if type = "contribution". Defaults to 0.75.
col.sel	The colour for selected genotypes. Defaults to "red".
col.nonsel	The colour for nonselected genotypes. Defaults to "gray".
legend.position	The position of the legend.
...	Other arguments to be passed from ggplot2::theme().

Value

An object of class gg, ggplot.
