## Description

Boxplot showing the Root Means Square Prediction Difference of of a cross validation procedure.

## Usage

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 ## S3 method for class 'cvalidation' plot( x, violin = FALSE, export = FALSE, order_box = FALSE, x.lab = NULL, y.lab = NULL, size.tex.lab = 12, file.type = "pdf", file.name = NULL, plot_theme = theme_metan(), width = 6, height = 6, resolution = 300, col.violin = "gray90", col.boxplot = "gray70", col.boxplot.win = "cyan", width.boxplot = 0.6, x.lim = NULL, x.breaks = waiver(), ... ) 

## Arguments

 x An object of class cvalidation fitted with the functions cv_ammi(), cv_ammif(), cv_blup(), or a bound object fitted with bind_cv(). violin Define if a violin plot is used with boxplot. Default is 'TRUE' export Export (or not) the plot. Default is T. order_box Logical argument. If TRUE then the boxplots will be ordered according to the values of the RMSPD. x.lab The label of x-axis. New arguments can be inserted as x.lab = 'my x label'. y.lab The label of y-axis. New arguments can be inserted as y.lab = 'my y label'. size.tex.lab The size of the text in axis text and labels. file.type 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. resolution The resolution of the plot. Parameter valid if file.type = 'tiff' is used. Default is 300 (300 dpi) col.violin Parameter valid if violin = T. Define the color of the violin plot. Default is 'gray90. col.boxplot Define the color for boxplot. Default is 'gray70'. col.boxplot.win Define the color for boxplot of the best model. Default is 'cyan'. width.boxplot The width of boxplots. Default is 0.2. 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) ... Currently not used.

## Details

Five statistics are shown in this type of plot. The lower and upper hinges correspond to the first and third quartiles (the 25th and 75th percentiles). The upper whisker extends from the hinge to the largest value no further than 1.5 * IQR from the hinge (where IQR is the inter-quartile range). The lower whisker extends from the hinge to the smallest value at most 1.5 * IQR of the hinge. Data beyond the end of the whiskers are considered outlying points.

## Value

An object of class gg, ggplot.
