thank you for your reply and the explanations. I have checked the R CMD
check on my system (MacOS Mojave) and the whole check does not exceed 1Gb
of RAM. I am also surprised why it would need that much, because all the
examples are pretty slim, so even if all objects are kept, I am wondering
why it needs that much RAM on Windows/Linux.
If you can give me some more hints I'd be glad.
