時間毎のtweetのretweet数とfavorite数の合計を求める。どの時間帯のtweetが一番反応が良いか？という簡易的な調査。

reaction_survey.rb

require 'twitter'

if ARGV[0].nil? || ARGV[0] == ''
  puts 'Usage:'
  puts '  ruby reaction_survey.rb [twitter user name]'
  exit
end
username = ARGV[0]

  config.consumer_secret = 'twitter consumer_secret'
  config.access_token = 'twitter access_token'
  config.access_token_secret = 'twitter access_token_secret'

  response.empty? ? collection.flatten : collect_with_max_id(collection,  response.last.id - 1,  &block)
end

  collect_with_max_id do |max_id|
    options = {:count => 200,  :include_rts => true}

  end
end

end

result.each_with_index do |point, hour|
  puts "#{sprintf("%02d", hour)}: #{point}"
