我正在尝试在我的 Dockerfile 中安装“ggpmisc”包,我收到了以下消息:
Installing package into ‘/usr/local/lib/R/site-library’
(as ‘lib’ is unspecified)
Warning: unable to access index for repository https://cloud.r-project.org/src/contrib:
cannot open URL 'https://cloud.r-project.org/src/contrib/PACKAGES'
Warning message:
package ‘ggpmisc’ is not available (for R version 3.5.0)
我该如何解决?
