Hello

I'm working with DNA microarrays and want to classify them with SVM. I
want to plot the results and it's imposible for me. I found others
tutorials and examples (with iris and cats data) where you can plot the
results with plot.svm, but you need to write a formula and I don't know
how to do this with golubEsets data, for example .

plot ( svm1, golubTrain, formula)

For example, Iris Data:

Sepal.Length Sepal.Width Petal.Length Petal.Width Species

1 5.1 3.5 1.4 0.2 setosa 2 4.9 3.0 1.4 0.2 setosa 3 4.7 3.2 1.3 0.2 setosa 4 4.6 3.1 1.5 0.2 setosa 5 5.0 3.6 1.4 0.2 setosa 6 5.4 3.9 1.7 0.4 setosa 7 4.6 3.4 1.4 0.3 setosa 8 5.0 3.4 1.5 0.2 setosa

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

plot(m2, iris, Petal.Width ~ Petal.Length, slice = list(Sepal.Width = 3,
Sepal.Length = 4))

I should be grateful if you would send me information about how to plot the golubEsets data (for example the formula, because I have tested several options but neither of them work). My data are very similar (expression values with several conditions), so I could plot my results if I knew how to plot golub data.

Thanks a lot

Beatriz
