show.position
a logical value indicating whether the sub-triangle containing the data should be
put back in the total triangle

Examples
if not NULL, a vector with 3 numbers between 0 and 1. Let notice that min3+max3
must equal c(1,1,1)
data(euro123)
par(mfrow = c(2,2))
x = rbind.data.frame(euro123$in78, euro123$in86, euro123$in97)
triangle.plot(x)
triangle.class(x, as.factor(rep("G",36)), csta = 0.5, cell = 1)
triangle.class(x, euro123$plan$an)
triangle.class(x, euro123$plan$pays)
triangle.class(x, euro123$plan$an, cell = 1, axesell = TRUE)

Triangular Plotting
Description
Usage
Graphs for a dataframe with 3 columns of positive or null values
triangle.plot is a scatterplot
triangle.biplot is a paired scatterplots
triangle.posipoint, triangle.param, add.position.triangle are utilitaries functions.
triangle.plot(ta, label = as.character(1:nrow(ta)), clabel = 0,
cpoint = 1, draw.line = TRUE, addaxes = FALSE, addmean = FALSE,
labeltriangle = TRUE, sub = "", csub = 0, possub = "topright",
show.position = TRUE, scale = TRUE, min3 = NULL, max3 = NULL,
