Optional graphical parameters

The following graphical parameters can optionally be added to customize the plot:

• cex: Numeric value, giving the amount by which text on the plot should be scaled relative to the default (which is 1).
• cex.axis: Amount by which axis annotations should be scaled, as numeric value.
• cex.lab: Amount by which axis labels should be scaled, as numeric value.
• circles: Manual definition of circles to be drawn, as numeric vector of the form c(inner circle, outer circle, interval between the circles).
• col: Colour to be used for the sectors.
• col.axis: Colour to be used for axis annotations -- default is"gray45".
• col.border: Colour to be used for sector borders -- default isNULL(no border is drawn).
• col.circle: Colour to be used for circles -- default is"gray45".
• col.cross: Colour to be used for axis lines -- default is"gray45".
• col.lab: Colour to be used for axis labels -- default is"black".
• fg: IfTRUE, sectors are plotted in foreground (on top of axis lines and circles) -- default isFALSE.
• lty.circle: Line type of circles -- default is"dashed". Seeparfor available line types.
• lty.cross: Line type of axis lines -- default is"solid". Seeparfor available line types.
• lwd.border: Line width of the sector borders -- default is0.5. Only used ifcol.borderis set.
• lwd.circle: Line width of circles, as numeric value -- default is0.7.
• lwd.cross: Line width of axis lines, as numeric value -- default is0.7.
• pos.axis: Position of axis labels in degree, as numeric value -- default is60.
• sec.space: Space between plotted sectors, as numeric value between0and1-- default is0.2.
