RPY2加载某些Bioconductor包失败

Question

最近我们的系统更新了R到3.2.1（在一个单独的位置）。从那以后，我就很难在rpy2中加载某些包。在

我所做的：

• 将LD_LIBRARY_PATH设置为当前路径
• 卸载然后重新安装rpy2
• 卸载，然后重新安装有问题的软件包

当我切换回以前的R安装时，它工作得很好（当然，对于旧的R版本，重新安装了rpy2）。而且它似乎并不影响所有的软件包。在

例如，加载“limma”就没有问题。但是加载'affy'时，我在python控制台中出现以下错误：

>>> from rpy2.robjects.packages import importr
>>> base = importr('affy')
/mnt/software/anaconda/envs/py2/lib/python2.7/site-packages/rpy2/robjects/packages.py:63: UserWarning: Error in dyn.load(file, DLLpath = DLLpath, ...) :

  return _reval(expr)

  env = _get_namespace(rname)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/mnt/software/anaconda/envs/py2/lib/python2.7/site-packages/rpy2/robjects/packages.py", line 438, in importr
    env = _get_namespace(rname)

  /mnt/software/R-3.2.1/lib64/R/library/preprocessCore/libs/preprocessCore.so: undefined symbol: R_NaN

在Ipython笔记本中：

我试着提出建议，但没有成功。在

我用的是R3.2.1，bioconductor 3.1，rpy2 2.6.1

谢谢！在

错误消息指向R包preprocessCore。 请重新安装。如果从iPython开始做任何事情：

from rpy2.robjects import r
r_src = """
source("http://www.bioconductor.org/biocLite.R")
biocLite("preprocessCore")
"""
r(r_src)

完成后，如果安装成功完成，它应该可以工作：
