package interflex

| 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.
