Question

我的笔记本电脑无法访问互联网，我正在尝试下载软件包rgdal。

我已经下载了rgdal_1.4-8.tar.gz，gdal-3.0.4.tar.gz和proj-6.3.2.tar.gz。我尝试使用以下方式分别通过源安装它们：

install.packages（'... / ... tar.gz'，type ='source'，repos = NULL）

但是它不起作用。这是错误消息

ERROR: cannot extract package from 'D:/Users/sn/Documents/R source packages/gdal-3.0.4.tar.gz'
Warning in install.packages :

在Windows上离线安装R软件包'rgdal'及其外部依赖项
