Hi,
I am trying to use tune.svm in e1071 package.
the command i use is
tobj <- tune.svm(labels, data= data, cost = 10^(1:2))
Should the last column of the 'data' contain the labels as well? I want to
use the linear kernel. But it gives me the error
"Error in model.frame.default(formula, data) : 'data' must be a data.frame,
not a matrix or an array"
Do you know why this might happen?
best,
salih
