Hello, Jessica,
Can you please elaborate what you're trying to find with that function.
If e.g. you want to find best parameters C and gamma for RBF model (SVM), you
can use grid.py, check here:

Function tune.control() in package e1071 is an R interface to this algorithm.
Best,
-Alex

Subject: [R] e1071 tune.control() random parameter
I'm not sure what the parameter specifies:
random
if an integer value is specified, random parameter vectors are drawn from the
parameter space.
What are the parameter vectors and what is the parameter space? What means
drawn?
greetings
Jessi
