I am trying to understand the usage of slice while plotting. Can any one
provide me with some explanation to it or point me to a resource where I
can read it in greater detail. I have an example from the usage page for
SVM.

 

library(MASS)

library(e1071)

data(iris)

m2 <- svm(Species~., data = iris)

plot(m2,iris, Petal.Width~Petal.Length)

readline(prompt = "Pause. Press <Enter> to continue...") plot(m2, iris,
Petal.Width ~ Petal.Length, slice = list(Sepal.Width=3, Sepal.Length=4
))

 

How do I decide Sepal.Width should be set to 3 and Sepal Length set to
4?

 

Thanks../Murli
