我尝试texreg在 R 中安装软件包，但出现以下错误：

> install.packages("texreg", "~/R/x86_64-unknown-linux-gnu-library/2.13/")

这是我的 R 安装的问题吗？我正在运行 2.13，但很遗憾无法升级，因为我在集群上。

className在 R-2.14.0 中引入。我建议尝试以前版本的 texreg 之一。

> db <- news()
> news(grepl("className",Text), db=db)
Changes in version 2.14.0:

BUG FIXES

    o   In principle, S4 classes from different packages could have the same
         name.  This has not previously worked.  Changes have now been
         installed that should allow such classes and permit methods to use
         them.  New functions className() and multipleClasses() are related
         tools for programming.
