Triangular Representation and Groups of points
Description
Function to plot triangular data (i.e. dataframe with 3 columns of
positive or null values) and a partition
Usage
triangle.class(ta, fac, col = rep(1, length(levels(fac))),
wt = rep(1, length(fac)), cstar = 1, cellipse = 0, axesell = TRUE,
label = levels(fac), clabel = 1, cpoint = 1, pch = 20, draw.line = TRUE,
addaxes = FALSE, addmean = FALSE, labeltriangle = TRUE, sub = "", csub = 1,
possub = "bottomright", show.position = TRUE, scale = TRUE, min3 = NULL,
max3 = NULL)
Arguments
ta |
a data frame with 3 columns of null or positive numbers |
fac |
a factor of length the row number of |
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 |
cpoint |
a character size for plotting the points, used with |
pch |
if |
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 |
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 |
