circ.n, circ.r 
Number of (main)circles or, alternatively, radius of circles to be drawn, which will be labeled. 
circ.col, circ.lwd 
Color and line width of circles. 
circ.cex 
Character size of labels of main circles in
multiples of 
circ.between 
Distance between labels of the main circle and the circle itself in multiples of circ.cex. 
circ.dir 
Direction along which the labels of the main circles should be drawn, measured clockwise as radian from North. 
circ.sub.n, circ.sub.r 
Number of subcircle intervals between two main circles, or, alternatively, the radii of all subcircles. 
circ.sub.col, circ.sub.lwd 
Color and line width of subcircles. 
cyclVar.lab 
Labels of cyclic variable placed along the outmost circle. 
cyclVar.cex 
Charactersize of labels of cyclic
variable in multiples of cex as defined in

cyclVar.between 
Distance between labels of the cyclic
variable and the outmost circle of the rose in multiples of

cyclVar.centered 
Labels are positioned relative
to their center. 
ray.lim 
Defines the values for the center and the maximum radius in user coordinates. Be careful with specifying the center different from 0 as this might result in misleading roses. 
ray.n 
Number of rays. 
Returns the arguments conveniently packaged up in a list to supply the arguments for the grid appearance of rose plot.
