you should find some useful information in the latest R news Volume 3/2, October 2003

refer page 8 where Paul's figure 2 shows some novel symbols showing "China Sea Wind Speed, Direction and Temperature"... plotted by lat.&long.

I sent a mail last week asking for some advise in relation to displaying wind vectors on a contour map of a region. Whilst I have had some useful feedback relating to the second part of this question (namely how to animate a time series of still frames), I haven't recieved any advise on how I might create the still images of the spatially distributed wind vector data at any given time point.
Firstly, is there a way in which I can input orographical information (x,y,z co ords) into R to create a map, secondly, is there a way in which i can superimpose a visual wind vector (i.e. arrow of certain length and certain orientation) onto such a map?
thanks in advance, Laura
