Triangle plot fill

Fill a triangle plot with smaller triangles.

Usage

triax.fill(col)

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.

 # the data will be something like response at different proportions
 fillval<-list(0,c(0,0.1,0),c(0,0.1,0.2,0.1,0),
  c(0,0.1,0.2,0.3,0.2,0.1,0),c(0,0.1,0.2,0.3,0.4,0.3,0.2,0.1,0),
  c(0,0.1,0.2,0.3,0.4,0.5,0.4,0.3,0.2,0.1,0),

  c(0,0,0,0.1,0.1,0.2,0.3,0.4,0.3,0.2,0.1,0.1,0,0,0))
 # use some method of converting values to colors
 fillcol<-sapply(fillval,function(x) {x*10+1} )
