How long does it generally take to install caret package in R?
在 R 中安装 caret 包通常需要多长时间？ I ran install.packages('caret', dependencies = TRUE), and R has been running the install for close to an hour now.我运行了 install.packages('caret', dependencies = TRUE)，R 已经运行了将近一个小时的安装。 Is this normal?这是正常的吗？

It shouldn't take that long, I actually had to install the Caret package on one of my machines earlier today and it took less than a minute.应该不会花那么长时间，实际上我今天早些时候必须在我的一台机器上安装 Caret 包，而且只花了不到一分钟的时间。 Sounds like you might want to check your connection speed.听起来您可能想检查您的连接速度。

With dependencies, it can take a while, mine took about 30mins and my download speed was around 18Mbps max, it had 648 dependencies as of Nov19.对于依赖项，可能需要一段时间，我的大约需要 30 分钟，我的下载速度最大约为 18Mbps，截至 11 月 19 日它有 648 个依赖项。 With-out dependencies, it is fast, as the answer from the_SJC suggests.没有依赖关系，它很快，正如 the_SJC 的答案所暗示的那样。

Using:使用：
install.packages("caret", dependencies = c("Depends", "Suggests"))
the install took about 5 hours for me with 100Mbps internet.使用 100Mbps 互联网安装对我来说大约需要 5 个小时。
Adding to that, it still didn't install what I needed.除此之外，它仍然没有安装我需要的东西。 This worked:这有效：
install.packages("caret", dependencies = TRUE)
it took about 10 minutes.花了大约 10 分钟。
