Graphical analysis of genotype-vs-environment interaction

Description

This function produces a line plot for a graphical interpretation of the genotype-vs-environment interaction. By default, environments are in the x axis whereas the genotypes are depicted by different lines. The y axis contains the value of the selected variable. A heatmap can also be created.

Usage

ge_plot(
.data,
env,
gen,
resp,
type = 1,
values = TRUE,
text_col_pos = c("top", "bottom"),
text_row_pos = c("left", "right"),
average = TRUE,
order_g = NULL,
order_e = NULL,
xlab = NULL,
ylab = NULL,
width_bar = 1.5,
heigth_bar = 15,
plot_theme = theme_metan(),
colour = TRUE
)


Arguments

 .data The dataset containing the columns related to Environments, Genotypes, replication/block and response variable(s). env The name of the column that contains the levels of the environments gen The name of the column that contains the levels of the genotypes. resp The response variable. type The type of plot type = 1 for a heatmap or type = 2 for a line plot. values Show the values in the plot? Defaults to TRUE. text_row_pos, text_col_pos The position of the text in the rows and columns. The defaults show the text at left and top. average Show the average values for environments and genotypes? Defaults to TRUE. order_g, order_e A charactere vector indicating the order of the levels for genotypes and environments, respectively. This can be used to change the default ordering of rows and columns. xlab, ylab The labels for x and y axis, respectively. width_bar, heigth_bar The width and heigth of the legend bar, respectively. plot_theme The graphical theme of the plot. Default is plot_theme = theme_metan(). For more details,see ggplot2::theme(). colour Logical argument. If FALSE then the plot will not be colored.

Value

An object of class gg, ggplot.
