bar_plot1: The first barplot of the ranks of genotypes

In rYWAASB: Simultaneous Selection by Trait and WAASB Index

The first barplot of the ranks of genotypes

Description

• bar_plot1() creates a bar plot for the new index (rYWAASB for individuals) for simultaneous selection of genotypes by trait and WAASB index using ggplot2.

Usage

bar_plot1(datap, lowt = FALSE)

Arguments

datap	The data set
lowt	A parameter indicating whether lower rates of the trait is preferred or not. For grain yield e.g. Upper values is preferred. For plant height lower values e.g. is preferred.

Value

Returns an object of class ⁠gg, ggmatrix⁠.

Examples

# Case 1:  Higher trait values are preferred. For instance grain yield
# in cereals is a trait which its higher values are preferred and ranking
# is performed from the higher to lower values i.e. 1st, 2nd, 3rd etc
# in maize dataset.

data(maize)
bar_plot1(maize) # or: bar_plot1(maize, lowt = FALSE)

# Case 2:  In this case, the lower values of the given trait are preferred.
# For instance days to maturity (dm) and plant height are traits where their
# lower values are preferred.

data(dm)
bar_plot1(dm, lowt = TRUE)
