Subject: Is this how you start a hash?

I'm looking at the code below but still not clear about how this hash
forms!  The author of a ruby book I read claimed that the code forms
hash.  Is it?

#not complete code, if you try to use it, it won't work!

require 'yaml'
require 'wordplay'

class Bot
attr_reader :name

def initialize(options)
 @name = options[:name] || "Unnamed Bot"
 begin
  @data = YAML.load(File.read(options[:data_file]))
 rescue
  raise "Can't load bot data"
 end
end
end

So, when you created hash, don't you have to initialize it with an empty
hash?  For example:  @name = {}?

Also when I try to use a snippet in irb:
 @name = options[:name] || "Unnamed Bot"
NameError: undefined local variable or method `options' for main:Object
  from (irb):1
  from :0

options is also in File.read(), it's acting like adding more element to
a hash.  Am I right?  Though irb tells a different story as if it's not
how you starting a hash.

I'm confused!
