pak install from source should fail, probably

[gaborcsardi]

This is difficult, because it probably should not fail on various CRAN servers that test pak w/o suggested packages.

OTOH, install.packages() never actually fails, so you can't use install.packages() in a Dockerfile and assume that the package is installed if it is successful:

root@0030e21bddf6:/opt# Rscript -e 'install.packages("zxzxzxzx")'
Installing package into ‘/usr/local/lib/R/site-library’
(as ‘lib’ is unspecified)
Warning message:
package ‘zxzxzxzx’ is not available for this version of R

A version of this package for your version of R might be available elsewhere,
see the ideas at
https://cran.r-project.org/doc/manuals/r-patched/R-admin.html#Installing-packages

root@0030e21bddf6:/opt# echo $?
