a data frame with 3 columns of null or positive numbers
fac
a factor of length the row number of ta
col
a vector of color for showing the groups
wt
a vector of row weighting for the computation of the gravity centers by class
cstar
a character size for plotting the stars between 0 (no stars) and 1 (complete star) for a line linking a point to the gravity center of its belonging class.
cellipse
a positive coefficient for the inertia ellipse size
axesell
a logical value indicating whether the ellipse axes should be drawn
label
a vector of strings of characters for the labels of gravity centers
clabel
if not NULL, a character size for the labels, used with par("cex")*clabel
cpoint
a character size for plotting the points, used with par("cex")*cpoint. If zero, no points are drawn
pch
if cpoint > 0, an integer specifying the symbol or the single character to be used in plotting points
draw.line
a logical value indicating whether the triangular lines should be drawn
addaxes
a logical value indicating whether the axes should be plotted
addmean
a logical value indicating whether the mean point should be plotted
labeltriangle
a logical value indicating whether the varliable labels of ta should be drawn on the triangular sides
sub
a string of characters for the graph title
csub
a character size for plotting the graph title
possub
a string of characters indicating the sub-title position ("topleft", "topright", "bottomleft", "bottomright")
show.position
a logical value indicating whether the sub-triangle containing the data should be put back in the total triangle
scale
a logical value for the graph representation : the total triangle (FALSE) or the sub-triangle (TRUE)
min3
if not NULL, a vector with 3 numbers between 0 and 1
max3
if not NULL, a vector with 3 numbers between 0 and 1. Let notice that min3+max3 must equal c(1,1,1)
