Description

The imagebar_s function is a tool for creating versatile stacked bar charts by filling the bars with external png and jpeg images.

Usage

imagebar_s(data, x, y, group, xlab = "", ylab = "", pattern.type,
  label.size = 3.5, frame.color = "black", frame.size = 1,
  legend.type = "h", legend.h = 6, legend.x.pos = 1.1,
  legend.y.pos = 0.49, legend.w = 0.2, legend.pixel = 20,
  bar.width = 0.9)

Arguments

data	the data to be used.
x	the variable used on x axis.
y	the variable used on y axis.
group	the variable used as the second grouping variable on x axis.
xlab	a character string to give x axis label.
ylab	a character string to give y axis label.
pattern.type	a list of objects returned by readPNG and readJPEG used to fill the stacked bars.
label.size	the font size of legend labels shown above the stacked bars.
frame.color	the color of the borders of the stacked bars.
frame.size	a numeric value, the line size for the borders of the stacked bars.
legend.type	if legend.type='h', the layout of legends is horizontal; if legend.type='v', the layout of legends is vertical.
legend.h	a numeric value to change the height of legend boxes.
legend.x.pos	a numeric value to change the position of legends on x axis.
legend.y.pos	a numeric value to change the position of legends on y axis.
legend.w	a numeric value to change the width of legends.
legend.pixel	a numeric value to change the pixel of legend boxes
bar.width	a numeric value to change the width of the bars.
