Look at package CircSpatial. You can certainly plot wind direction by x and y coordinates. You probably could use color to show speed, but it's not immediately clear from the documentation or examples. You can browse some examples by going to the R Graphical Manual at http://rgm2.lab.nig.ac.jp/RGM2/ and then typing package:CircSpatial into the search box.
