Question

我已经在macOS中通过Home-brew安装了R：

brew install R

但是，现在，我需要切换版本并安装特定的R版本。因此，我尝试通过两种方式安装R-3.5.2均未成功：

brew install R-3.5.2
brew install R@3.5.2

这就是我得到的：

Error: No available formula with the name "r@3.5.2" 
==> Searching for a previously deleted formula (in the last month)...
Warning: homebrew/core is shallow clone. To get complete history run:
  git -C "$(brew --repo homebrew/core)" fetch --unshallow

Error: No previously deleted formula found.
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
==> Searching taps...
==> Searching taps on GitHub...
Error: No formulae found in taps.

你有什么主意吗？谢谢：）

免责声明：我没有可用于测试的Mac。

Here，您会找到一个非常有用的教程，了解如何通过自制软件安装旧版本，here是另一本教程。

对于R来说，它表示为：

git clone https://github.com/Homebrew/homebrew-core.git
cd homebrew-core/
git log master -- Formula/r.rb

对于R 3.5.2产生以下提交：

    r 3.5.2

    Closes #35321.

您也可以通过URL搜索提交（请参阅this注释）：

https://github.com/Homebrew/homebrew-core/search?q=r%203.5.2&type=commits

相应地，您应该能够通过（最新的R 3.5.2提交）安装R 3.5.2：

brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/e66b3a288ee5e68c3c04e95705b7311c9f76bdf2/Formula/r.rb

或：

brew install https://github.com/Homebrew/homebrew-core/raw/e66b3a2/Formula/r.rb

article中提到的

brew switch和brew pin也可能很有趣。
