[R] wind rose (oz.windrose) scale

[Uwe Ligges]

Looking at the code shows that the author forgot to scale the plot 
appropriately at all, since xlim/ylim is hardcoded:

     plot(0, xlim = c(-20, 20), ylim = c(-20, 20), type = "n",
         axes = FALSE, xlab = "", ylab = "", ...)

Hence you may want to fix it and provide the patch to the package 
maintainer or contact the maintainer (CCing) of the package and ask him 
to fix it.

Best,
Uwe Ligges
