This function represents a simplified barchart adapted to display eigen values. The bar color depends on whether the axis is displayed, kept or not.
plotEig(eigvalue, nf, xax = 1, yax = 2, col.plot = "black", col.kept = "grey",
col = "white", facets = NULL, plot = TRUE, storeData = FALSE, pos = -1, ...)An object of class ADEg (subclass C1.barchart).
The result is displayed if plot is TRUE.
a numeric vector of eigenvalues
the number of retained factors, NULL if not provided
an integer indicating which factor is plotted on the x-axis
an integer indicating which factor is plotted on the y-axis
a color value to fill the bar corresponding to the displayed factors
a color value to fill the bar corresponding to the kept by not displayed factors
a color value to fill the bar corresponding to the other factors
a factor splitting the rows of dfxy so that subsets
of the data are represented on different sub-graphics
a logical indicating if the graphics is displayed
a logical indicating if the data should be stored in
the returned object. If FALSE, only the names of the data
arguments are stored
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 storeData is
FALSE
additional graphical parameters (see
adegpar and trellis.par.get)

Graphical parameters for bars are available in ppolygons of adegpar.
Some appropriated graphical parameters in p1d are also available.
