显示[R ggplots内嵌在jupyter笔记本

Question

我试图运行在这里发现了一个简单的例子：https://www.datacamp.com/community/blog/jupyter-notebook-r#gs.OczVCjA

import warnings 
warnings.filterwarnings('ignore') 
# Load in the r magic 

import rpy2.ipython 

%reload_ext rpy2.ipython 

# We need ggplot2 

%R require(ggplot2) 
%R library("ggplot2") 
# Load in the pandas library 
import pandas as pd 
# Make a pandas DataFrame 
df = pd.DataFrame({'Alphabet': ['a', 'b', 'c', 'd','e', 'f', 'g', 'h','i'], 
        'A': [4, 3, 5, 2, 1, 7, 7, 5, 9], 
        'B': [0, 4, 3, 6, 7, 10,11, 9, 13], 
        'C': [1, 2, 3, 1, 2, 3, 1, 2, 3]}) 
# Take the name of input variable df and assign it to an R variable of the same name 
%R -i df 
# Plot the DataFrame df 
ggplot(data=df) + geom_point(aes(x=A, y=B, color=C)) 

起初，我不得不

我加入％R到NameError“定义ggplot节点”最后一行，现在得到以下的输出：

是一场阴谋创建以及如何在笔记本内嵌显示它像一个将与matplotlib吗？

NB：我内Jupyter使用命令康达安装-CR 4 R 5 - 要领（？至极通常包括ggplot）如上述

好安装R，我想现在... 这为我工作：

%R print(ggplot(data=df) + geom_point(aes(x=A, y=B, color=C)))

您必须添加一个print()声明。不知道为什么。
