从 Matlab 调用 R

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，尽管当我从 shell 运行它时一切正常。我运行的是 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':

取消设置环境变量DYLD_LIBRARY_PATH在调用 R 脚本之前：

>> !/usr/bin/Rscript ms.R
