[Rd] if(--as-cran)?

[Spencer Graves]

Hi, Duncan et al.:


       I modified my CRAN() function (see below) to look for 
"_R_CHECK_TIMINGS_" and "R_CHECK_TIMINGS", but got "NOT CRAN" with "R 
CMD check --as-cran" from both.


       Suggestions?
       Thanks,
       Spencer
p.s.  This is fda available from R-Forge via "svn checkout 
svn://svn.r-forge.r-project.org/svnroot/fda/".  It currently is 
programmed to stop no matter what.  I want it to give an error "CRAN" 
with "R CMD check --as-cran" and "NOT CRAN" without "--as-cran".  
Currently, I get "NOT CRAN" for both.
