This can be overridden with R_CHECK_FORCE_SUGGESTS_=false which may be
helpful if Suggests: has a long tail of dependencies, or a shorter test run
is desired.

The R Internals manual describes the variable as 

  '_R_CHECK_FORCE_SUGGESTS_'
       If true, give an error if suggested packages are not available.
       Default: true (but false for CRAN submission checks).

which highlights the different behaviour under --as-cran and without.
