difference between inner and outer plotting radius.
name.padding
offset for variable names.
name.cex
character expansion for variable names.
axis.circ
location to draw axis circles.
x.group
optional grouping vector for X variables.
y.group
optional grouping vector for Y variables.
type
one of “correlation” or “variance”, depending on the type of data to be displayed.
Details
Helio plots display data in radial bars, with larger values pointing outward from a base reference circle and smaller (more negative) values pointing inward). Such plots are well-suited to the display of multivariate information with several groups of variables, as with canonical correlation analysis.
Value
None.
