我们正在笨手笨脚地让一些 R 代码在生产环境中工作，作为其中的一部分，我们安装了一些 R 包，如下所示：
# Default directories and mirrors
WORKING_DIR <- "/srv/foo/bar/baz"
LIB_DIR <- paste( WORKING_DIR, "libs", sep="/" )
setwd(WORKING_DIR)
stringi.loc <- paste( WORKING_DIR, "stringi_0.4-1.tar.gz", sep="/" )
这可能不是安装 R 包的最优雅的方式，但它似乎对我们来说没问题（任何其他关于 R 包管理的提示都会受到欢迎，但在这个阶段有点晚了:)。
但是， stringi 软件包似乎依赖于 icu52l 软件包，它通过网络安装：

我们如何告诉它寻找本地副本？输出方便地包括远程位置（http://static.rexamine.com/packages/icudt52l.zip）所以我们可以把它放在我们自己的某个地方，但不确定在哪里。
也许我们的处理方式完全错误，但欢迎任何帮助或指示。
我们在 ubuntu 机器上也尝试安装 libicu42 和 libicu-dev 但这些似乎都没有帮助。
