Default Panel Function for bwplot

Description

This is the default panel function for bwplot.

Usage

panel.bwplot(x, y, box.ratio = 1,
             horizontal = TRUE,
             pch, col, cex, 
             font, fontfamily, fontface, 
             fill, varwidth = FALSE,
             ...,
             levels.fos,
             stats = boxplot.stats,
             coef = 1.5,
             do.out = TRUE)

Arguments

`x, y`	numeric vector or factor. Boxplots drawn for each unique value of `y` (`x`) if `horizontal` is `TRUE` (`FALSE`)
`box.ratio`	ratio of box height to inter box space
`horizontal`	logical. If FALSE, the plot is ‘transposed’ in the sense that the behaviours of x and y are switched. x is now the ‘factor’. Interpretation of other arguments change accordingly. See documentation of `bwplot` for a fuller explanation.
`pch, col, cex, font, fontfamily, fontface`	graphical parameters controlling the dot. `pch="\|"` is treated specially, by replacing the dot with a line (similar to `boxplot`)
`fill`	color to fill the boxplot
`varwidth`	logical. If TRUE, widths of boxplots are proportional to the number of points used in creating it.
`stats`	a function, defaulting to `boxplot.stats`, that accepts a numeric vector and returns a list similar to the return value of `boxplot.stats`. The function must accept arguments `coef` and `do.out` even if they do not use them (a `...` argument is good enough). This function is used to determine the box and whisker plot.
`coef, do.out`	passed to `stats`
`levels.fos`	numeric values corresponding to positions of the factor or shingle variable. For internal use.
`...`	further arguments, ignored.

Details

Creates Box and Whisker plot of x for every level of y (or the reverse if horizontal=FALSE). By default, the actual boxplot statistics are calculated using boxplot.stats. Note that most arguments controlling the display can be supplied to the high-level bwplot call directly.
