[R-pkg-devel] Warning in dir.create(vd2 <- "vign_test"): 'vign_test' already exists

[Spencer Graves]

Hello, All:


       Under Windows 10, "R CMD check sos_2.0-1.tar.gz" cloned from 
"https://github.com/sbgraves237/sos" ends with:


* checking rebuild of vignettes outputs ...Warning in dir.create(vd2 <- 
"vign_test"):  'vign_test' already exists


       Under macOS 10.15.3 it finishes fine.


       "grep 'vign_test'" failed to find anything.


       ???
       Thanks,
       Spencer Graves


p.s.  Running R 3.6.3 on both machines with "update.packates()" clean.
