[R-pkg-devel] help interpreting a response from CRAN

[Roy Mendelssohn - NOAA Federal]

I have found win-builder timings come close,  but only close.  My experience is that the CRAN timings were uniformly slower than those on win-builder.  But I also find that I can get quite significant differences between win-builder-release and win-builder-devel.  So I also take the slowest that I can find as a basis,  and assume the actual times will be slower than that.

HTH,

(I will obviously do my best by doing arithmetic on the tests that I set to be skipped, but it would be nice to be able to double-check without wasting everyone's time ... I guess if I knew that CRAN submissions would *always automatically* be rejected with Windows test times>10 min, I could use CRAN submission itself as my test ... but maybe that's a bad idea?)
