[R-pkg-devel] Tests run without --as-cran and not with

[Jan van der Laan]

Thanks! That looks relevant.

I think I have found the relevant source code in pandoc, and it seems it 
just calls Rscript without path. So it will probably call the dummy 
Rscript. Hmm, I'll have to think how to fix that.

It is probably good that R CMD check checks this as this could cause 
weird errors when people have multiple versions of R on their system.

Best,
Jan
