我曾尝试在Colab中运行演示文稿“用PYTHON和R可视化演示的多语言数据分析”
但它说，懒散的人是不存在的
当我尝试将其安装为foloows时
%%R
install.packages("lazyeval")
它的输出像

R[write to console]: trying URL 'https://cran.rstudio.com/src/contrib/lazyeval_0.2.2.tar.gz'

不幸的是，Presentation项目似乎无法添加问题
在SO Using R in Python with Rpy2: how to ggplot2?有一个帖子，上面有代码
import numpy as np
import pandas as pd
import rpy2.robjects.packages as packages
import rpy2.robjects.lib.ggplot2 as ggplot2
import rpy2.robjects as ro
R = ro.r
datasets = packages.importr('datasets')
mtcars = packages.data(datasets).fetch('mtcars')['mtcars']
gp = ggplot2.ggplot(mtcars)
pp = (gp
+ ggplot2.aes_string(x='wt', y='mpg')
+ ggplot2.geom_point(ggplot2.aes_string(colour='qsec'))
+ ggplot2.scale_colour_gradient(low="yellow", high="red")
+ ggplot2.geom_smooth(method='auto')
+ ggplot2.labs(title="mtcars", x='wt', y='mpg'))
pp.plot()
R("dev.copy(png,'/tmp/out.png')")
但在Colab中，它只是输出
R[write to console]:
geom_smooth()using method = 'loess' and formula 'y ~ x'
IntVector with 1 elements. 5

那是6年前的演讲。它应该使用当时使用的Python和R版本（以及它们各自的包，也包括当时的版本）运行
否则，一些内容会被添加到rpy2文档或其他最近的文章中
