思いつく限りしてみたのですが・・・
require 'pp'
ary = %w(w1 w2 w3 w4 w2 w3 w1 w1 w5 w2 w3 w4)
col = %w(w1 w2 w3 w9)
zero = ary.uniq.inject(Hash.new){|h,w| h[w] = 0 ; h }
window = 6
hout = Hash.new
ary.each_with_index do |key,i|
(hout[key] = zero.dup) unless hout.key?(key)
ary[i+1,window].select{ |e| e != key }.each { |word| hout[key][word] += 1 }
end
pp hout
ar=Hash.new;ar.default=0;ar= hout.values[0].values_at(*col)
p ar
hout.each_pair do |k,v|
if col.include?(k)
puts "#{k}\t#{v.values_at(*col)}"
end
end
# >> {"w1"=>{"w1"=>0, "w2"=>4, "w3"=>4, "w4"=>3, "w5"=>2},
# >> "w2"=>{"w1"=>4, "w2"=>0, "w3"=>5, "w4"=>2, "w5"=>1},
# >> "w3"=>{"w1"=>4, "w2"=>2, "w3"=>0, "w4"=>3, "w5"=>2},
# >> "w4"=>{"w1"=>2, "w2"=>2, "w3"=>1, "w4"=>0, "w5"=>1},
# >> "w5"=>{"w1"=>0, "w2"=>1, "w3"=>1, "w4"=>1, "w5"=>0}}
# >> ["w1", "w2"]
# >> [0, 4, 4, nil]
# >> w1 044
# >> w2 405
# >> w3 420
arにkeyが存在しなければnilではなくて0にしたいのですが何かどうすればいいでしょうか？
