[R-SIG-Mac] Setting _R_CHECK_DEPENDS_ONLY_=true

[Koenker, Roger W]

Ok,  this worked as I expected so _R_CHECK_DEPENDS_ONLY_=true  now reveals the same problem that CRAN detected, which was easily fixed.  But I’m left with a NOTE with a large number of HTML warnings that begin with:

* checking HTML version of manual ... NOTE
Found the following problems:
Bosco.Rd:4:1: Warning: <link> inserting "type" attribute
Bosco.Rd:12:1: Warning: <script> proprietary attribute "onload"
Bosco.Rd:12:1: Warning: <script> inserting "type” reattribute


Are these deadly from a CRAN perspective?  And if so, any hints about how to fix them?  Googling only produced the following thread:   https://github.com/htacg/tidy-html5/issues/377

I now interpret this to mean that I should install 4.2, create this directory and reinstall packages so that they appear there rather than under the RHOME directory.   If someone could confirm this or suggest an alternative strategy I’d be most grateful.
