"memory not mapped" error during system() call

[meik michalke]

hi,

i'm trying to rebuild the binary packages for the repo with R 3.5 now, but 
RKWard seems to have a problem with running a system call.

let's say that "~/software/R/R-3.4.4/lib64/R" is a standalone installation of 
R 3.4.4 (i always have several of those to build binaries for multiple 
versions) and "~/package/roxyPackage" is the source code for roxyPackage.

when i call

 system("R_HOME=\"~/software/R/R-3.4.4/lib64/R\" ~/software/R/R-3.4.4/bin/R 
CMD build --no-manual --md5 ~/package/roxyPackage")

i get this error in RKWard:

<error>
* checking for file ‘~/package/roxyPackage/DESCRIPTION’ ... OK
* preparing ‘roxyPackage’:
* checking DESCRIPTION meta-information ... OK
* installing the package to build vignettes
* creating vignettes ... ERROR

NA, call. = FALSE)})
16: tools::buildVignettes(dir = ".", tangle = TRUE)

</error>


if i run the same code from a plain R session, it just works like it should:

<noerror>
* checking for file ‘~/package/roxyPackage/DESCRIPTION’ ... OK
* preparing ‘roxyPackage’:
* checking DESCRIPTION meta-information ... OK
* installing the package to build vignettes
* creating vignettes ... OK
Warnung: ‘inst/doc’ files
    ‘roxyPackage_vignette.Rmd’, ‘roxyPackage_vignette.html’,  
‘roxyPackage_vignette.R’
  ignored as vignettes have been rebuilt.
  Run R CMD build with --no-build-vignettes to prevent rebuilding.
* checking for LF line-endings in source and make files and shell scripts
* checking for empty or unneeded directories
* adding MD5 file
* building ‘roxyPackage_0.06-2.tar.gz’
</noerror>


so i guess it's an issue with RKWard's R console, maybe?
