R SIG Debian - Oct 2017 - Problem when installing lme4 under Debian stretch

I am a new user in the Linux environment and recently encountered an error
when trying to install the car package. The error was related to
installation of a dependency (lme4). Here is the output from the
installation:

* installing *source* package ?lme4? ...
** package ?lme4? successfully unpacked and MD5 sums checked

I am using Raspbian Stretch with a Raspberry Pi. Might someone have a
suggestion about how to proceed?  Many thanks in advance!

I would start with the _binary_ package you can install via

   sudo apt-get install r-cran-car

which will take care of all dependecies.

Building some of these package on small hardware can be challenging simply
due to lack of RAM --- and ditto for minimal cloud instances with small RAM
footprint.  Use binaries where you can if you hardware cannot cope.

Thanks very much, Dirk! I gave that a try and got the following:
pi at raspberrypi:~ $ sudo apt-get install r-cran-car
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 r-cran-car : Depends: r-api-3
              Depends: r-cran-pbkrtest but it is not going to be installed
              Depends: r-cran-quantreg but it is not going to be installed
E: Unable to correct problems, you have held broken packages.


Given the message, should I assume that lme4 (and car) cannot be installed
on my setup?  Many thanks in advance!
