  ...
)

Arguments

• x: The waasb object
• var: The variable to plot. Defaults to var = 1 the first variable of x.
• which: Which plot to shown. If which = "gen" (default) plots the BLUPs for genotypes. To create a plot showing the BLUPs for genotype-environment combinations, use which = "ge".
• ncol, nrow: The number of columns and rows, respectively, to be shown in the plot when which = "ge".
• prob: The probability error for constructing confidence interval.
• export: Export (or not) the plot. Default is TRUE.
• file.type: If export = TRUE, define the type of file to be exported. Default is pdf, Graphic can also be exported in *.tiff format by declaring file.type = "tiff".
• file.name: The name of the file for exportation, default is NULL, i.e. the files are automatically named.
• plot_theme: The graphical theme of the plot. Default is plot_theme = theme_metan(). For more details, see ggplot2::theme().
• width: The width "inch" of the plot. Default is 6.
• height: The height "inch" of the plot. Default is 6.
• err.bar: Logical value to indicate if an error bar is shown. Defaults to TRUE.
• size.err.bar: The size of the error bar for the plot. Default is 0.5.
• size.shape: The size of the shape (both for genotypes and environments). Default is 3.5.
• size.tex.lab: The size of the text in axis text and labels.
• height.err.bar: The height for error bar. Default is 0.3.
• x.lim: The range of x-axis. Default is NULL (maximum and minimum values of the data set). New arguments can be inserted as x.lim = c(x.min, x.max).
• x.breaks: The breaks to be plotted in the x-axis. Default is authomatic breaks. New arguments can be inserted as x.breaks = c(breaks)
• col.shape: A vector of length 2 that contains the color of shapes for genotypes above and below of the mean, respectively. Default is c("blue", "red").
• y.lab: The label of the y-axis in the plot. Default is "Genotypes".
• x.lab: The label of the x-axis in the plot. Default is NULL, i.e., the name of the selected variable.
• n.dodge: The number of rows that should be used to render the Y 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.
• panel.spacing: Defines the spacing between panels when which = "ge".
• resolution: The resolution of the plot. Parameter valid if file.type = "tiff" is used. Default is 300 (300 dpi)
• ...: Currently not used.

Returns

An object of class gg, ggplot.
