[英]I keep getting a knit error with my markdown file in R
I am receiving this error when trying to knit my R markdown sheet我在尝试编织我的 R markdown 表时收到此错误
Error in contrib.url(repos, "source"): trying to use CRAN without setting a mirror calls: ... withVisible -> eval -> eval -> install.packages -> contrib.url Execution halted contrib.url 中的错误(repos,“source”):尝试使用 CRAN 而不设置镜像调用:... withVisible -> eval -> eval -> install.packages -> contrib.url 执行停止
Does anyone have any experience with this?有人对这个有经验么?
Without the exact code, it is difficult to assess the problem.如果没有确切的代码,就很难评估问题。 However, as @NelsonGon writes, this is usually the error from running an installation (
install.packages()
inside a chunk.但是,正如@NelsonGon 所写,这通常是运行安装的错误(
install.packages()
在块内。
Instead, the library should be installed beforehand and loaded with library(example
) inside a chunk to make it available for the markdown environment.相反,应该预先安装该库并在一个块中加载
library(example
),以使其可用于 markdown 环境。
