Subject: tune(): how to specify a kernel ?
I would like to use tune() for tuning parameters for svm method, but it is
not clear
to me how to specify a kernel.
I am trying to use something like this:
> obj <- tune(svm, Species~., data = iris, ranges = list(kernel =
c('radial', 'linear')))
Error in pmatch(x, table, duplicates.ok) :
argument is not of mode character
but it generates an error.
