RグラフィックスクックブックをSageで試してみる
Rグラフィックスクックブック ―ggplot2によるグラフ作成のレシピ集 にでている例題をpython版ggplotで試し、ggplotでサポートしていない部分はRのggplot2をSageから操作してプロットしてみました。
Sageでデータをプロットするときに参考にしてください。

連続値をカテゴリに変換する
Pandasを使って連続値の区間で区切って処理する方法の紹介です。知っていると便利です。
age = np.array([20, 22, 25, 27, 21, 23, 37, 31, 61, 45, 41, 32])
sex = np.array(['F', 'M', 'M', 'M', 'F', 'M', 'F', 'M', 'F', 'M', 'F', 'M'])
df = pd.DataFrame({'age': age, 'sex': sex})
df
age sex 0 20 F 1 22 M 2 25 M 3 27 M 4 21 F 5 23 M 6 37 F 7 31 M 8 61 F 9 45 M 10 41 F 11 32 M [12 rows x 2 columns] age sex 0 20 F 1 22 M 2 25 M 3 27 M 4 21 F 5 23 M 6 37 F 7 31 M 8 61 F 9 45 M 10 41 F 11 32 M [12 rows x 2 columns] |
# カテゴリ分けする区切り値
bins = [18, 25, 35, 60, 100]
cat_names = ['youth', 'YoungAdult', 'MiddleAged', 'Senior']
df['bins'] = pd.cut(df.age, bins, labels=cat_names)
df.head()
age sex bins 0 20 F youth 1 22 M youth 2 25 M youth 3 27 M YoungAdult 4 21 F youth [5 rows x 3 columns] age sex bins 0 20 F youth 1 22 M youth 2 25 M youth 3 27 M YoungAdult 4 21 F youth [5 rows x 3 columns] |
