  main_y = 0.2,
  main_adj = 0,
  main_cex = 0.9,
  main_font = 2,
  width = NULL,
  xlim = NULL,
  ylim = c(0, 2.2),
  asp = 1,
  labels_y = 1.55,
  label_cex = NULL,
  mar = c(0, 0, 0, 1),
  par_reset = TRUE,
  filename = NULL,
  pdf_width = 8,
  pdf_height = 2.5
)

Arguments

x	Color, vector: One or more colors that R understands
main	Character: Title. Default = NULL, which results in deparse(substitute(x))
bg	Background color.
main_col	Color: Title color
main_x	Float: x coordinate for main.
main_y	Float: y coordinate for main.
main_adj	Float: adj argument to mtext for main.
main_cex	Float: character expansion factor for main.
main_font	Integer, 1 or 2: Weight of main 1: regular, 2: bold.
width	Float: Plot width. Default = NULL, i.e. set automatically
xlim	Vector, length 2: x-axis limits. Default = NULL, i.e. set automatically
ylim	Vector, length 2: y-axis limits.
asp	Float: Plot aspect ratio.
labels_y	Float: y coord for labels. Default = 1.55 (rhombi are fixed and range y .5 - 1.5)
label_cex	Float: Character expansion for labels. Default = NULL, and is calculated automatically based on length of x
mar	Numeric vector, length 4: margin size.
par_reset	Logical: If TRUE, reset par settings on exit.
filename	Character: Path to save plot as PDF.
pdf_width	Numeric: Width of PDF in inches.
pdf_height	Numeric: Height of PDF in inches.

Value

Nothing, prints plot.
