从Matlab调用R.

Question

我曾经能够通过系统调用从Matlab调用R:

system('"/usr/bin/R" --no-save < myscript.R')

但是现在,使用Matlab R2012b和R版本3.0.0(2013-04-03) - "Masked Marvel",我在加载库时遇到错误,即使从shell运行它时一切正常.我正在运行MacOSX 10.6.8.

Error in dyn.load(file, DLLpath = DLLpath, ...) : 
unable to load shared object'/Library/Frameworks/R.framework/Versions/3.0/Resources/library/stats/libs/stats.so':
dlopen(/Library/Frameworks/R.framework/Versions/3.0/Resources/library/stats/libs/stats.so, 6):

DYLD_LIBRARY_PATH在调用R脚本之前取消设置环境变量:

>> !/usr/bin/Rscript ms.R
Error in dyn.load(file, DLLpath = DLLpath, ...) :
