无法安装软件包‘ggpmisc’是不可用的(对于R版本3.5.0)

Question

我试图在我的Dockerfile中安装‘ggpmisc’包，我收到了这样的消息：

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) 

我怎么才能修好它？

Answer 1

cloud.r-project.org应该是cran.rstudio.com的别名，但是看起来r-project.org的名称服务出现了问题。您可以直接使用install.packages("ggpmisc", repos = "https://cran.rstudio.com")来尝试实名。
