There's loads of packages in the Machine Learning R Task View:

http://cran.r-project.org/web/views/MachineLearning.html

for example: package e1071 (http://cran.r-project.org/web/packages/
e1071/index.html) has a function called svm()

Hi,

I use ksvm() in the kernlab package. If I recall correctly it's quite easy to implement, and has a choice of different kernals.

The simplest to use is probably svm() in package e1071 or svmlight() 
in klaR, both interfaces to well respected SVM code (but e1071 
includes the C++ code it uses).
