Dear all,

the problem arise since the original CircStats package (the Splus version)
distribute a version of eqscplot function without help and copyright
statement. That is why I have considered it as an internal function
from this package.

Now that, thanks to Prof. Ripley, I know where the function come from I
will erase the function from the next release of the package and include
MASS package in the required package.
