Thanks, please do not comment out your examples and use \donttest{} instead:

\examples{
   examples for users and checks:
   executable in < 5 sec

   donttest{
       further examples for users (not used for checks)
   }
}


Please ensure that your functions do not write by default or in your
examples/vignettes/tests in the user's home filespace. That is not allow
by CRAN policies. Please only write/save files if the user has specified
a directory. In your examples/vignettes/tests you can write to
tempdir(). E.g.

myfile <- file.path(tempdir(), "ic.ics")
ic_write(ic, myfile)```
