安装R包fGarch时出错

Question

我试图安装R包fGarch一段时间，但似乎有一个问题。我使用以下命令：

import rpy2.interactive as r
import rpy2.interactive.packages 
rlib = r.packages.packages
r.packages.importr("utils")
package_name = "fGarch"
rlib.utils.install_packages(package_name)

安装过程基本正常，除了最后的警告：

/home/vdesai/anaconda/lib/python2.7/site-packages/rpy2/robjects/packages.py:216:   UserWarning: Conflict when converting R symbol in the package "tools" to a Python symbol (package.dependencies -> package_dependencies while there is already package_dependencies)
warn(msg)

当我尝试使用以下命令加载程序包时：

%R library(fGarch)

我得到以下错误：

Error in library(fGarch) : there is no package called ‘fGarch’
In addition: Warning messages:
1: In (function (pkgs, lib, repos = getOption("repos"), contriburl = contrib.url(repos,     :
installation of package ‘MASS’ had non-zero exit status
2: In (function (pkgs, lib, repos = getOption("repos"), contriburl = contrib.url(repos,  :
installation of package ‘fBasics’ had non-zero exit status
3: In (function (pkgs, lib, repos = getOption("repos"), contriburl = contrib.url(repos,  :
installation of package ‘fGarch’ had non-zero exit status
Error in library(fGarch) : there is no package called ‘fGarch’

请注意，使用Rstudio中的这个包不会造成任何困难。有人能帮帮忙吗？

Answer 1

我找到了以下问题的答案。其主要思想是1)安装anaconda，它提供了一个很好的python发行版2)通过conda运行命令来安装R："conda install -- rpy2 https://conda.binstar.org/r r“3)通过运行"conda install -- https://conda.binstar.org/r https://conda.binstar.org/r rpy2”来安装通道。

现在，如果您尝试从ipython notebook安装fGarch，我过去常常在安装依赖项MASS时遇到错误。但这些依赖项在conda channel r中以软件包的形式提供，我们可以使用以下命令安装它们: conda install --channel https://conda.binstar.org/r r-mass install --channel https://conda.binstar.org/r r-fbasics那么，您应该能够从ipython notebook安装fGarch。

这种方法的好处是，如果事情没有按计划进行，您可以随时删除包目录或整个anaconda目录。因此，它很容易进行实验。
