[Rd] objects intermittently shared between vignettes

[Spencer Graves]

Hello:


       Is it widely known that objects not explicitly deleted from one 
vignette in a package can be available to a second in "R CMD build" and 
"R CMD check" but not when the second vignette is built manually, at 
least under RStudio on Mac OS X 10.11.4 using R 3.3.0?


        For an example, see


install.packages("pkgW2vignettes", repos="http://R-Forge.R-project.org")


       This package contains two toy vignettes.


       This is not a big deal, but it spooked me, when I saw 227 objects 
listed by "objects()" in a vignette built by "R CMD build" + "R CMD 
check", when the same "objects()" command only listed 4 objects when I 
built the same vignette by itself from within RStudio.


       Enjoy,
       Spencer Graves
