setting INSTALL_opts

[kkmann]

Dear all,

is there a way of setting INSTALL_opts with pkg_install() - I would like to install tests with "--install-tests" but there seems to be no way of passing that through pkg_install().

There isn't currently. Why do you want to install the tests?

I was hoping to run them after installation as basic integration tests. renv allows this this via options(), see https://stackoverflow.com/questions/68890715/install-r-package-with-specific-version-and-tests but I would love to use the automagic sys deps installation and parallel features of pak. Tagging @michaelmayer2.

edit: seems that you just set INSTALL_opts = "", how about exposing that via an INSTALL_opts global option?

pak/R/safe-cran-install.R

Line 6 in 141068f

install_one <- function(pkg, lib = .libPaths()[1], INSTALL_opts = "", ...) {

That means that you cannot install these packages from binaries, though. Is that OK?

What are you going to do if a test fails? Sporadic test failures do happen.

That is not the line/file that pak uses for installation, it is rather here:
https://github.com/r-lib/pkgdepends/blob/6741f04bf5f7fc8d73d87b3a326b1bf5a3914a38/R/install-plan.R#L393-L397

But in any case, we can add support for this.

Absolutely - we consider using an internal offline package manager snapshot (only sources), that's why the parallel installation feature of pak is so great :)

Despair and run some kind of mitigation strategy or at least document a test failure. Sometimes restarting might help even if it is not Windows. If tests consistently fail, keep a record of those, assess them, and then diff against this log of 'safe fails'.

Great, thx 🚀.
