将ggvis更新为0.4.3后，我构建的闪亮应用程序不再有效。因此，当我运行以下代码时，我正在尝试将ggvis恢复为以前的版本：
foo <- "https://cran.r-project.org/src/contrib/Archive/ggvis/ggvis_0.4.2.tar.gz"
install.packages(foo, repos=NULL, type="source")
基于这篇文章：Installing older version of R package
这是控制台中的结果。我已经用＆＃34; company＆＃34;替换了目录中公司和用户的名称。和＆＃34;用户＆＃34;分别为自由裁量权。

Warning in install.packages :

结果是ggvis保持为版本0.4.3。
我尝试使用完全相同的代码在Mac上运行相同版本的RStudio（3.3.1）的另一台机器上恢复到0.4.2，而不是我的Windows机器，它运行得很好。我不知道为什么我无法在我的机器上重新安装0.4.2的ggvis。 感谢
