我使用coefplot 2绘制生态数据的回归估计。我有一台新电脑，所以刚刚安装好。所有其他软件包和代码都可以用于新的设置。但是非常喜欢继续使用coefplot 2，但需要帮助。
我曾尝试使用R forge和bolker源站点安装coefplot 2，在这里和其他网站的几个帖子中推荐如下，没有运气。

install.packages("coefplot2", repos="http://www.math.mcmaster.ca/bolker/R", type="source")

install.packages("coefplot2",repos="http://r-forge.r-project.org")

> install.packages("coefplot2", repos="http://www.math.mcmaster.ca/bolker/R", type="source")

已经安装了以前的依赖项，例如安装要求安装“重塑”。我想知道我是否需要安装'rtools'。似乎很傻，因为我不是一个开发人员-但如果它的工作，我会这样做。
