scatter.dudi {ade4} | R Documentation |
performs the scatter diagrams of objects of class dudi
.
scatter.dudi(x, xax = 1, yax = 2, clab.row = 0.75, clab.col = 1, permute = FALSE, posieig = "top", sub = NULL, ...)
x |
an object of class dudi |
xax |
the column number for the x-axis |
yax |
the column number for the y-axis |
clab.row |
a character size for the rows |
clab.col |
a character size for the columns |
permute |
if FALSE, the rows are plotted by points and the columns by arrows. If TRUE it is the opposite. |
posieig |
if "top" the eigenvalues bar plot is upside, if "bottom" it is downside, if "none" no plot |
sub |
a string of characters to be inserted as legend |
... |
further arguments passed to or from other methods |
scatter.dudi
is a factorial map of individuals and the projection of the vectors of the canonical basis multiplied by a constante of rescaling. In the eigenvalues bar plot,the used axes for the plot are in black, the other kept axes in grey and the other in white.
