Zoe, If you use a Wind Rose diagram (e.g., http://rgm2.lab.nig.ac.jp/RGM2/func.php?rd_id=circular:wind rose), which are available in several packages, you could plot tidal speed and direction Wind Rose diagrams in a x-y plot to plot location. If you used the lattice package, this could give you th

You can use the 'my.symbols' and 'ms.arrows' functions in the TeachingDemos package to plot arrows at given locations with specified angles, lengths, and colors. On Sat, Jun 16, 2012 at 5:16 AM, zoeita wrote: > Hi, > > I have had a look around the forums and I can't seem to find anything that > w

Hi The devil is in the detail of the components so here is a toy example to give you an idea in 2D but 5D It is somewhat easier to interpret if you condition. You may be able to visualize in 3D not all can. 3D can be a problem if distinguishing points are 180 degrees apart in the preferred vie

Hi, I have had a look around the forums and I can't seem to find anything that works with my data. I have lats, longs, time, tidal speed and direction and need to plot this in an xy plot to determine changes over time. contour and cloud have been recommended to me as a way to do this but I can't
