[R-pkg-devel] Rd cross-references ... NOTE, Undeclared packages ... in Rd xrefs

[Spencer Graves]

Hello, All:


	  How do I fix "Rd cross-references ... NOTE
Undeclared packages ‘EnvStats’, ‘drc’, ‘zoo’, ‘prodlim’, ‘plyr’, 
‘TRAMPR’, ‘raster’ in Rd xrefs"?


	  This occurs with 
"https://www.r-project.org/nosvn/R.check/r-devel-linux-x86_64-fedora-clang/Ecfun-00check.html" 
and with 
"https://www.r-project.org/nosvn/R.check/r-devel-linux-x86_64-fedora-clang/Ecdat-00check.html". 
  However, this error is not raised on other platforms.  My search for 
this note produced essentially the same message for other packages but 
no advice on how to fix it.


	  These are references to other packages that I do not use in my 
packages but that some users may wish to consider.  If needed, I will 
add them to "Suggests" for the packages.  However, that seems overkill, 
because I do not use them myself.  ???


	  Thanks,
	  Spencer Graves
