Hi there,
Is there a function in R that can draw vector density plot? The vector
density plot example can be found here:
http://reference.wolfram.com/mathematica/ref/VectorDensityPlot.html
As for the vector field plot, I found a function that has been posted in
this mailing list:
https://stat.ethz.ch/pipermail/r-help/2007-November/147005.html
I also referred to rasterVis package for the vectorplot function.
However, I don't figure out how to plot for field (-y, x) or something
like that.
Any help will be really appreciated.
Best,
Jinsong
