plot.sh: Plot the Smith-Hazel index

In metan: Multi Environment Trials Analysis

Plot the Smith-Hazel index

Description

Makes a radar plot showing the individual genetic worth for the Smith-Hazel index

Usage

## S3 method for class 'sh'
plot(
  x,
  SI = 15,
  radar = TRUE,
  arrange.label = FALSE,
  size.point = 2.5,
  size.line = 0.7,
  size.text = 10,
  col.sel = "red",
  col.nonsel = "black",
  ...
)

Arguments

x	An object of class sh
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().
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.
col.sel	The colour for selected genotypes. Defaults to "red".
col.nonsel	The colour for nonselected genotypes. Defaults to "black".
...	Other arguments to be passed from ggplot2::theme().

Value

An object of class gg, ggplot.

Examples

library(metan)
vcov <- covcor_design(data_g, GEN, REP, everything())
means <- as.matrix(vcov$means)
pcov <- vcov$phen_cov
gcov <- vcov$geno_cov

index <- Smith_Hazel(means, pcov = pcov, gcov = gcov, weights = rep(1, 15))
plot(index)
