Fill a triangle plot with smaller triangles.

Usage

Arguments

col

List of colors (see Details).

Details

In order for triax.fill to fill an existing plot that has been created by a call to triax.plot, the user must supply a list of fill colors. The first element of the list must begin with at least one value that can be interpreted as a color. The second element must begin with at least three such values, and so on, adding two values for each element of the list. Each list element will be displayed as a row of colored triangles starting at the top of the plot. The number of elements in the list determines the number of rows that will be displayed.

Value
