当我已经安装了软件包时，我正在拼凑有关如何安装软件包开发版本的说明，但我有点困惑。我的具体需要是安装开发版本，lme4以便我可以使用该predict功能。

首先，我知道我应该找到 的开发版本lme4，我已经（在一般意义上）在这个 URL上找到了它。我正在运行 Mac OSX 10.6.8 (Snow Leopard) 和 R 版本 2.14.1，因此我导航到正确的文件夹并下载*.tgz文件。但是当我尝试使用命令安装包时：

install.packages("~/Downloads/lme4_0.99999911-2.tgz", repos = NULL)

我收到一条错误消息，说明：

Warning in install.packages :
  package ‘~/Downloads/lme4_0.99999911-2.tgz’ is not available (for R version 2.14.1)

(1) 我如何找出需要运行哪个版本的 RI 才能访问包的开发版本，以及 (2) 我如何更新我的 R 版本和/或替换预先存在的版本lme4？

更新：

我使用以下命令尝试了另一种方法：

> library("devtools")
> install_github("lme4",user="lme4")

不幸的是，这会产生输出..

谢谢！希望我的问题对那里的其他 R 新手有用... 更新 2

根据上面的输出，我已经升级到 R 3.0.0。但是，现在当我尝试安装已下载的软件包时出现以下错误：

> install.packages("~/Downloads/lme4_0.99999911-2.tgz", repos = NULL)

Warning in install.packages :

(as ‘lib’ is unspecified)
'.path.package' is deprecated.
Use 'path.package' instead.
