[Rd] problematic dev.off() after running examples without plots

[Thierry Onkelinx]

Dear all,

When running R CMD check on our package, we get an error on the examples.

Error in grDevices::dev.off() :
     cannot shut down device 1 (the null device)

None of the examples in our package generates plots. grDevices::dev.off()
is code added by R CMD check. A workaround is to have at least one example
which has some plot. Is there a better solution? We are using R 3.5.1

Best regards,
