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.-

I have started using the circular package but it is not recognizing the function arrows.circular.  I attempted to use the example provided in the circular manual.  Here is the example code using the circular package:

 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)

My error is:  Error: could not find function "arrows.circular"

Any help would be greatly appreciated.  Thanks.
