scatterutil {ade4} | R Documentation |
These are utilities used in graphical functions.
The functions scatter use some utilities functions :
defines the layer of the plot for all scatters
defines the layer of the plot for sco functions
plots the polygons of the external contour
plots the eigenvalues bar plot
plots an inertia ellipse for a weighting distribution
puts labels on a correlation circle
puts labels centred on the points
plots a grid and adds a legend
puts a legend of values by square size
puts a legend by squares and grey levels
adds a legend of grey levels for the areas
to fit a plot on a background bipmap
plots a star for a weighting distribution
adds a string of characters in sub-title of a graph
is used to rotate labels
