In patternplot: Versatile Pie Charts, Ring Charts, Bar Charts and Box Plots using Patterns, Colors and Images

Description

The imageboxplot function is a tool for creating versatile boxplots by filling the boxplots with external png and jpeg images.

Usage

imageboxplot(
  data,
  x,
  y,
  group = NULL,
  xlab = "",
  ylab = "",
  label.size = 3.5,
  pattern.type,
  frame.color = "black",
  linetype = "solid",
  frame.size = 1,
  outlier.shape = 21,
  outlier.color = "black",
  outlier.size = 1,
  legend.type = "h",
  legend.h = 6,
  legend.x.pos = 1.1,
  legend.y.pos = 0.49,
  legend.w = 0.2,
  legend.pixel = 0.3,
  legend.label
)

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.
label.size	the font size of legend labels.
pattern.type	a list of objects returned by readPNG and readJPEG used to fill boxplots.
frame.color	the color for the borders of boxplots.
linetype	the linetype for the borders of boxplots.
frame.size	a numeric value, the line size for the borders of boxplots.
outlier.shape	the shape of outlier dots.
outlier.color	the color of outlier dots.
outlier.size	the size of outlier dots.
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 fine-tune the width of legend boxes on y axis.
legend.x.pos	a numeric value to change the position of legend text on x axis.
legend.y.pos	a numeric value to change the position of legend text 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.
legend.label	a vector to name legend labels.
