Dear R-help community,

I have searched through the archives and not been able ot find any advice on how to plot a wind field with one arrow per grid square with the arrow pointing in the direction of the wind and it's size proportional to the wind strength.

I have the wind speed data in arrays of [lon,lat,uwind] and [lon,lat,vwind] so it is broken down into u and v components. How do I plot it though?!?!

Any suggestions very wecome indeed - I seem to have hit a brick wall.....

All the best,
