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.
