package interflex

| Cheers - my response mixes up the order of things:
| 
| The suggested apt way INSTALLED INTERFLEX nicely. Lesson learned: install
| dependencies from apt if a package/library isn't in apt search.
| 
| Yes I also tried install.packages('interflex'). RStudio console complained
| about the same packages like this:
| ERROR: dependency 'xyz' is not available for package ''abc"
| * removing '/home/............/4.3/abc'
| Warning in install.packages?:
| ?installation of package 'abc' had non-zero exit status.

That can happen when a compile-from-source fails for lack of a (for
compilation from source) needed -dev packages.

Which is why _reliable_ and _complete_ provision of binaries is such a game
changer. I have been at this for 20+ years (as it was that long ago that
injected the first few r-cran-* packages into Debian).

And having r2u is a complete gamechanger.

I can drop into a random code repository (as today for work), run my
`installDeps.r` helper to install everything, or in the demo for you just do
`install.r interflex` (or, if one prefers run it as an R command via eg a
simple `Rscript -e 'install.packages("interflex")'`).

And getting all of that in under 30 seconds _reliably_ is pure magic.
 
| ok, AFAIU, wanting to manage R?dependencies as easily as possible suggests
| using Ubuntu with r2u instead of Debian. Be my guest to evaluate this
| interpretation.

It would be sweet if we could do something like r2u for Debian, but for now
we can't.  Switching between Debian and Ubuntu is not that onerous though.

|     | I'd like input on how to install interflex
|     | <https://github.com/xuyiqing/interflex> (note the instructions on its
|     | github).
| 
|     It says? ?install.packages("interflex")? ?-- did you try that?
| 
|     | The installation failed on stable/bullseye, also when I updated to the
|     | newer R version 4.3.0 through secure apt and the additional source.list
|     | <https://cran.r-project.org/bin/linux/debian/#secure-apt> element.
|     | 1. $ `sudo apt r-base-dev`
|     | 2. RStudio install.packages('pacman')
|     | 3. RStudio pacman::p_load('interflex')
| 
|     Sorry but that is non-standard and not what a) the R documentation suggests
|     or b) the package itself suggests.? You're on your own there; maybe try the
|     RStudio / posit help forums for pacman.?
| 
|     My preference these days is r2u (on Ubuntu 22.04) and a quick
| 
|     ? ?$ time docker run --rm -ti rocker/r2u:22.04 install.r interflex
| 
|     succeeded in 22 seconds (!!) installing a total of 91 (!!) different .deb
|     packages. I like r2u a _lot_ for this ease, speed and reliability of fully
|     dependency-declared .deb packages (for Ubuntu 22.04 and 20.04, NOT for
|     Debian).? See? ?https://eddelbuettel.github.io/r2u/? ?for more.

| 
|     There is a saying that you try to walk before you run. _Many_ of those
|     packages failing to install from source (== harder, you need dependencies,
|     and also slower) are in fact available as r-cran-xyz package for
|     Debian. Try 'apt-cache search r-cran-xyz' for different values of xyz.
