1. AKB48総選挙データのスクレイピング
1-1. Webからデータを読み込む
・Rを使うと、Webサイトから文字情報や数字情報を読み込んで、データフレームを作ることができる。
・ここでは AKB48総選挙のホームページ(http://www.akb48.co.jp/sousenkyo_45th/result.php) から、Rを使って、データを読み取ってみる。
・AKB48の総選挙のホームページ上には次のようなデータが掲示されている。
・例えば、第一位の指原莉乃さんのデータは次のように表示されている。
・上記表示に該当するソースを確認する。
・「表示」→「開発/管理」→「ソースを表示」を選ぶ。
・Rを使ってWebサイトに接続し、ソース情報を一括で取得し、result と名前をつける。
result = readLines("http://www.akb48.co.jp/sousenkyo_45th/result.php", encoding = "UTF-8")・読み取ったデータ result の最初の8行を表示してみる。
head(result)[1] "<?xml version=\"1.0\" encoding=\"UTF-8\"?>"
[2] "<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\">"

[4] "<head>"
[5] "<meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\" />"
[6] "<meta http-equiv=\"Content-Style-Type\" content=\"text/css\" />" 1-2. 必要な情報（票数）だけを選別する
・AKB48総選挙のホームページの「ソースを表示」を見る。
・集めたい情報（票数）は result_count の後にある。
・最初にgrep()関数を使って、ソースの一括情報 result から得票数のデータだけを選別
→ result_count と名前をつける。
result_count = grep("result_count", result)・うまく取り出せたか、先頭6行を確認。
head(result[result_count])[1] "\t\t <p class=\"result_count\">243,011票</p>"
[2] "\t\t <p class=\"result_count\">175,613票</p>"
[3] "\t\t <p class=\"result_count\">112,341票</p>"
[4] "\t\t <p class=\"result_count\">110,411票</p>"
[5] "\t\t <p class=\"result_count\">92,110票</p>"
[6] "\t\t <p class=\"result_count\">78,279票</p>" ・gsub()関数を使って、票数以外の文字を消す。
gsub(".*<p class=\"result_count\">(.*)票</p>","\\1", result[result_count]) [1] "243,011" "175,613" "112,341" "110,411" "92,110" "78,279" "69,159"

[78] "13,366" "13,204" "13,058" ・カンマが入っていると文字列になってしまうので
→gsub()関数を使って、カンマを消す。
→as.integer()関数を使って、数字を関数化する。
→関数化したものに akb_count と名前をつける。
akb_count = as.integer(gsub(",", "",
gsub(".*<p class=\"result_count\">(.*)票</p>","\\1", result[result_count])))・うまくできたか確認。

・同様に、メンバーの名前を取得する。
result_name = grep("result_name", result)・うまく取り出せたか、先頭6行を確認。
