[R] e1071 tune.control() random parameter

[Alekseiy Beloshitskiy]

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

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
