[R] R CMD check message that I can't figure out (.onLoad failed)

[stephen sefick]

I have been able to track and fix everything so far with R CMD check.
How do I make this reproducible and I will do it.

this is the message that I got:

Error in fun(...) : couldn't connect to display ":0.0"
Error : .onLoad failed in 'loadNamespace' for 'tcltk'

annoying little problems of being mammals.
