如何不需要用户输入 install.packages(type = "both") [英] How to not need user input for install.packages(type = "both")

问题描述

通常情况下，install.packages(..., type = "both") 如果有需要从源代码构建的包，则需要用户输入.

Normally, install.packages(..., type = "both") requires user input if there is a package that needs to be built from source.

例如(目前，使用 R 3.5.1)，install.packages(c("feather", "tidyr"), type = "both")) 将从二进制和从源头开始，只要用户在进行羽毛安装时单击是".

For example (currently, with R 3.5.1), install.packages(c("feather", "tidyr"), type = "both")) will install tidyr from binary and feather from source, as long as there is a user to click "yes" when it gets to the feather install.

有没有办法通过install.packages()的一些选项自动点击是，或者不需要用户输入?

Is there a way to automatically click yes, or not require user input through some of the options to install.packages()?

注意: install.packages(..., type = "source") 不需要用户输入，但它构建所有包，这不是理想的在这种情况下的行为.

Note: install.packages(..., type = "source") does not require user input, but it builds all packages, which is not the desirable behavior in this case.

推荐答案

install.packages.compile.from.source 选项可以设置为 "always" 以从源代码安装软件包而不提示用户界面.默认为"interactive"，使用type="both"时会提示用户确认.

The install.packages.compile.from.source option can be set to "always" to install packages from source without prompting for UI. The default is "interactive", which will prompt for user confirmation when using type="both".

解决方案:

options(install.packages.compile.from.source = "always")
install.packages(c("feather","tidyr"), type = "both")
