缺少 RODBC 1.3-16

Question

我正在尝试安装 RODBC

install.packages('RODBC')

并返回错误：

Retrieving 'https://cran.rstudio.com/src/contrib/RODBC_1.3-16.tar.gz' ...
Warning messages:
1: curl: (22) The requested URL returned error: 404 Not Found 
2: curl: (22) The requested URL returned error: 404 Not Found 

上面的网址确实是返回页面未找到。我真的需要 1.3-16 版本，因为我在 R 3.6.0 上安装它。

有什么解决办法吗？

Answer 1

该软件包的最新版本是 1.3-17。来自官方 CRAN 文档 (link)：

RODBC：ODBC 数据库访问 ODBC 数据库接口。

版本：1.3-17 取决于：R (≥ 4.0.0)

安装 R 的 4.X.X 版本并再次尝试使用 install.packages 函数安装它。

如果您想继续使用较旧的 R 版本，请使用此方法安装以前的软件包版本：

require(devtools)
install_version("RODBC", version = "1.3-16")
