我无法安装 RDCOMClient，使用 R-3.6
一些背景:
RDCOMClient 在我的 R-3.51 实例中工作，我需要使用 3.6，我需要使用 RDCOMClient 与我桌面的 Outlook 交互。 mailR 和 sendmailR 目前不是一个选项。
我试过的事情:
>install.packages("RDCOMClient")

我怀疑 RDCOMClient 不支持 3.6，因为它不在此处的目录中: http://www.omegahat.net/R/bin/windows/contrib/ ，但我想在继续之前我会在这里尝试。
有什么我可以做的吗？
最佳答案
事实并非如此，RDCOMClient 不支持 R3.6。它只是还没有(还)用 3.6x 编译并放置在存储库“http://www.omegahat.net/R/bin/windows/contrib/3.6/”中当前版本的子目录中。但是使用 R 3.5x 编译的 0.93-0 版本与 R 3.6x 完全兼容，只需从 3.5 目录“http://www.omegahat.net/R/bin/windows/contrib/3.5.1/”下载并从本地 PC 安装为 zip。
或者直接做
url <- "http://www.omegahat.net/R/bin/windows/contrib/3.5.1/RDCOMClient_0.93-0.zip"
install.packages(url, repos=NULL, type="binary")
