R，Python：在rpy2上安装软件包 [英] R, Python: install packages on rpy2

问题描述

我在Python脚本中通过 rpy2 库使用 R ，我需要一个包不在R的默认安装中。如何安装？

I'm using R in my Python script through the rpy2 library and I need a package that is not in the default installation of R. How can I install it?

install.packages("DirichletReg", repos="http://r-forge.r-project.org")

不起作用。

在Python上：

>>> install.packages("DirichletReg", repos="http://r-forge.r-project.org") 
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'install' is not defined

来自R：

> install.packages("DirichletReg", repos="http://r-forge.r-project.org")
Installing package(s) into ‘/usr/local/lib/R/site-library’
(as ‘lib’ is unspecified)
Warning message:
In getDependencies(pkgs, dependencies, available, lib) :
  package ‘DirichletReg’ is not available (for R version 2.14.1)

推荐答案

这个怎么样

>>> import rpy2.interactive as r
>>> r.importr("utils")
>>> package_name = "DirichletReg"
>>> r.packages.utils.install_packages(package_name)
