Normally, install.packages(..., type = "both") requires user input if there is a package that needs to be built from source.
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.
Is there a way to automatically click yes, or not require user input through some of the options to install.packages()?
Note: install.packages(..., type = "source") does not require user input, but it builds all packages, which is not the desirable behavior in this case.
回答1:
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".
Solution:
options(install.packages.compile.from.source = "always")
install.packages(c("feather","tidyr"), type = "both")
