3章 その10 階層的クラスタの出力
名前付き引数をインクリメントだと勘違いしてた。
printclust(clust.left, labels=labels, n=n+1)
のn=n+1はpythonでは名前付き引数なので、別にインクリメントしているわけじゃなかった。
cluster.rbにprintclust関数を追加
http://www.bitbucket.org/shokai/collective-intelligence-study/src/cadaac71b6aa/03/clusters.rb
# 階層型クラスタを出力する def printclust(clust,labels=nil,n=0) # 階層型レイアウトにするためにインデントする n.times do print ' ' end if clust.id < 0 # 負のidはこれが枝である事を示している puts '-' else # 正のidはこれが終端だということを示している if labels == nil puts clust.id else puts labels[clust.id] end end # 右と左の枝を表示する printclust(clust.left, labels, n+1) if clust.left != nil printclust(clust.right, labels, n+1) if clust.right != nil end
再帰してどんどん書いていく。rubyに名前付き引数は無いっぽいのでn+1だけになった
動かす
test.rbとして保存
require 'clusters.rb' cs = Clusters.new blognames,words,data = cs.readline('myblogdata.txt') clust = cs.hcluster(data) cs.printclust(clust, blognames)
ruby test.rb > blogname-tree
