[R-pkg-devel] winbuilder - missing global definitions / error in example latex code stdout

[Sven E. Templer]

Hello everybody,

i uploaded a package to the win-builder.r-project.org (R-devel) and received a 00check.log that NOTifiEs about missing visible global functions. Please see 
http://win-builder.r-project.org/WZnnzaSqBse4/00check.log 
at the lines following: 
* checking R code for possible problems ... NOTE

This is not happening on local Darwin and Linux (64bit) (R 3.2.3) checks, nor on the win-builder R-release, e.g. see
http://win-builder.r-project.org/a83iezxtXSg4/00check.log

Despite, on both win-builder checks, I recognized errors (not on local Darwin and Linux) running examples that print latex code (see the logs from above).

Two questions:

a) Is the 'missing global functions' issue in win-builder R-devel a planned change in the R future release, so one will need to import base functions in future, or is it an unsolved issue in the developmental stage?

b) Is it (also for Linux and Darwin) suggested to '\dontrun{}' examples with standard output (esp. in latex code)?

Many thanks for enlightening me,
Sven
