plot.mgidi: 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 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,
  size.point = 2.5,
  size.line = 0.7,
  size.text = 3.5,
  width.bar = 0.75,
  col.sel = "red",
  col.nonsel = "gray",
  legend.position = "bottom",
  ...
)

Value

An object of class gg, ggplot.

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".
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().
