Ternary plot with a partition in classes (levels of a factor)
Description
This function represents a three dimensional scatter plot with a partition in classes (levels of a factor).
Usage
1 2 3 4 
Arguments
dfxyz 
a three columns data frame used to produce the plot 
fac 
a factor (or a matrix of factors) splitting the rows of 
wt 
a vector of weights for 
labels 
a character vector containing the class' labels 
col 
a logical, a color or a colors vector to color points, ellipses, labels, lines and polygons 
ellipseSize 
a positive number for ellipse size 
starSize 
a number between 0 and 1 for the size of the stars segments joining the stars' center (centroids) and the matching points 
chullSize 

adjust 
a logical to adjust the device with the limits of the smaller equilateral triangle containing the values 
min3d 
a vector of three values for triangular minimal limits 
max3d 
a vector of three values for triangular maximal limits 
showposition 
a logical indicating whether the used triangle should be shown in the complete one 
facets 
a factor splitting the rows of 
plot 
a logical indicating if the graphics is displayed 
storeData 
a logical indicating if the data are stored in
the returned object. If 
add 
a logical. If 
pos 
an integer indicating the position of the
environment where the data are stored, relative to the environment
where the function is called. Useful only if 
... 
additional graphical parameters (see

Value
An object of class ADEg
(subclass Tr.class
) or ADEgS
(if showposition
is TRUE,
if add
is TRUE
and/or if facets are used).
The result is displayed if plot
is TRUE
.
