ggplot2 不存在于 python 的 rpy2 中？
我正在 Python3.2 中使用 rpy2 v2.1.9，我不明白为什么我不能使用库 ggplot2
import rpy2
from rpy2.robjects import r
r.library("ggplot2")
这是我收到的错误消息
Error in function (package, help, pos = 2, lib.loc = NULL, character.only = FALSE, :
there is no package called 'ggplot2'
Traceback (most recent call last):

I am working with rpy2 v2.1.9 in Python3.2, I don't understand why I can't use the library ggplot2
