我是Python的新手(以及一般的编程)我来自金融背景,所以请耐心等待.我刚开始使用Python(Enthought的Pylab/Scipy/Numpy)和R进行统计分析.我正在尝试将rpy2安装到Python中以集成R,但我得到错误:

试图猜测R的HOME但在PATH中没有R命令.

我不确定这意味着什么.我的R.exe的路径是"C:\ Program Files\R\R-2.12.1\bin",如果它有用的话.任何帮助将非常感激!

这是setup.py的代码

import os, os.path, sys, shutil, re, itertools
from distutils.command.build_ext import build_ext as _build_ext
from distutils.command.build import build as _build

from distutils.core import setup
from distutils.core import Extension


pack_name = 'rpy2'
pack_version = __import__('rpy').__version__


class build(_build):
    user_options = _build.user_options + \
        [
        #('r-autoconfig', None,
        # "guess all configuration paths from " +\
        #     "the R executable found in the PATH " +\
        #     "(this overrides r-home)"),
        ('r-home=', None, 
         "full path for the R home to …

我正在尝试安装rpy2,我正面临一个共同的问题.不幸的是,我找到的所有解决方案都是针对win7的

我安装了Python 2.7和R 2.15.然后我在终端上写字

easy_install rpy2

或者,或者

pip install rpy2

相同的结果:

Tried to guess R's HOME but no R command in the PATH

我该做什么？

我一直在尝试安装rpy2模块,所以我可以在我的Python脚本中使用R函数,但是在遵循这些页面的建议后我收到错误:

1) 试图猜测R的HOME但在PATH中没有R命令.OsX 10.6

2) http://rpy.sourceforge.net/rpy2/doc-dev/html/overview.html

到目前为止我做了什么:

1)编辑我的路径环境变量以包括"C:\ Program Files\R\R-3.1.0\bin\x64;"

2)创建一个名为"R_HOME"的新环境变量,并将其值设置为"C:\ Program Files\R\R-3.1.0"

3)创建一个名为"R_USER"的新环境变量,并将其值设置为"Hefin"(我的Windows用户名)

然后在我的命令提示符下输入:

easy_install rpy2

据我所知,easy_install已正确设置和安装.

我得到的输出是:
