More granularly, one of these five workflow spawns nine builds of which the
ones with older R version (3.3, 3.4, 3.5) fail as seen eg for run #3:

Maybe you want to comment out runs for R versions that old, or debug why they
fail. The error shown in R 3.5 (a version soon three years out of date you
are not obliged to care for: CRAN uses only current, previous and next
release) is not something I have seen before:

  ── R CMD build ─────────────────────────────────────────────────────────────────
  * checking for file ‘.../DESCRIPTION’ ... OK
  * preparing ‘CECPfuns’:
  * checking DESCRIPTION meta-information ... OK
  Error in parse_Rd("/tmp/RtmpydYbB0/Rbuild4d3e1cce5e37/CECPfuns/man/getCSC.Rd",  : 
    Value of SET_STRING_ELT() must be a 'CHARSXP' not a 'NULL'
  Execution halted
  Error: Error in proc$get_built_file() : Build process failed
  Calls: <Anonymous> ... build_package -> with_envvar -> force -> <Anonymous>
  Execution halted
  Error: Process completed with exit code 1.

Here proce$get_built_file points to `pkgbuild` which is part of a non-CRAN
toolchain.  So this may not be caused by your package -- I can't tell. My
preference is to keep it simpler: I usually get by with one workflow and
generally at most two builds.
