Hi David, You need to load the package before running your code: # install.packages('circular') require(circular) plot(rvonmises(10, circular(0), kappa=1)) arrows.circular(rvonmises(10, circular(0), kappa=1)) arrows.circular(rvonmises(10, circular(0), kappa=1), y=runif(10), col=2) arrows.circular(rvonmises(10, circular(0), kappa=1), y=runif(10), x0=runif(10, -1, 1), y0=runif(10, -1, 1), col=3) HTH, Jorge.- On Fri, Feb 10, 2012 at 11:55 AM, Chosid, David (MISC) <> wrote: I have started using the circular package but it is not recognizing the function arrows.circular.
