[R] rosavent problem

[Joshua Wiley]

I am wondering if there is a pattern in the rest of your data.  I made
a table based on the data you provided, using 0s for degrees 80-350,
and it plots fine.  If your data only changed slightly from section to
section (lets say by 4 or 5) it might be hard to tell that it is
actually different on the graph.  You could also try
rosavent(yourdata, fint=1) ## this just blows up the graph and might
make it easier to see small differences.
