This function is an EXACT copy of the function RosediagRad() in the circular package. As the function is not exported by the original package, I have copied it here to resolve the note thrown by devtools::check()
copyOfRosediagRad(

)a vector, matrix or data.frame. The object is coerced to class circular.
the zero of the plot. Ignored if plot.info or template are provided.
the rotation of the plot. Ignored if plot.info or template are provided.
number of arcs to partition the circle with.
logical: if TRUE, the rose diagram cells are "upper"-closed intervals.
make possible to choose sector radius form: square-root of relative frequency (sqrt, default) or conventional linear scale (linear).
numerical constant determining the radii of the sectors. By default, prop = 1.
the colour to draw the border. The default, NULL, means to use par("fg"). Use border = NA to omit borders.
the colour for filling the rose diagram. The default, NULL, is to leave rose diagram unfilled. The values are recycled if needed.
No return value, adds to an existing plot.
