Arguments

data	A data.frame.
x	A named character value. Evaluates to a column.
y	A named character value. Evaluates to a column.
group	A character value. Evaluates to a column.
facet_x	A character value. Evaluates to a column.
facet_y	A character. Evaluates to a column.
size	theme size for use_theme(). Default is 14.
width	Width of bar.
reorder	A character vector specifying the group variables to reorder. Default is c("group", "facet_x", "facet_y").
palette	Colour function.
labels_y	label formatting function
labels_x	label formatting function
label_pos	Position of labels. Can be "auto", "inside", "top", "both" or "none".
rescale_y	Rescaling factor for y-axis limits
label_cutoff	Cutoff size (proportion of y data range) for excluding labels
use_theme	ggplot theme function
position	Either "stack" (default), "fill" or "dodge"
facet_scales	Option passed to scales argument in facet_wrap or facet_grid. Default is "fixed".
legend_ncol	Number of columns in legend.
coord_flip	logical (default is FALSE). If TRUE, flips the x and y coordinate using ggplot2::coord_flip()

Value

A ggplot object.
