Hi,
This mailing list provides support for the ggplot2 plotting package
in R. From what you have written, it doesn't appear that you are
seeking help with plotting in ggplot2, but how to do SVM in a spatial
setting.
If your problem is specifically about R, it may be appropriate
to ask on the r-help list. However, going from what you have written
it looks like you have more general lack of knowledge about how to
fit SVM, and spatial SVM in particular. In this case, try searching
on the web and then constructing a question to ask on
stats.stackexchange.com or an equivalent machine learning site.
Regards,
Ron.
